*Steps to reproduce:*
1. Start HBase cluster with more than one regionserver.
2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*

*Steps to reproduce:*
1. Start HBase cluster with more than one regionserver.
2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*

2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*

bq. How does the ClusterConnection become stale?
I have already mention that issue is somewhere in AsyncRpcClient.java and i
think i have found cause why connection becomes stale. Here is code snippet
from AsyncRpcClient#crateRpcChannel():
{code}
362 rpcChannel = connections.get(hashCode);
363if (rpcChannel == null) {
364 rpcChannel = new AsyncRpcChannel(this.bootstrap, this, ticket,
serviceName, location);
355 connections.put(hashCode, rpcChannel);
266 }
{code}
We are getting connection (actually RPC channel ) from:
{code}
94 private final PoolMapInteger, AsyncRpcChannel connections;
{code}
without checking if channel is alive and ending up with closed channel when
regioserver is restarted. I have fixed this issue by checking if channel is
alive and replacing old one with new channel if is not.
{code}
363if (rpcChannel == null || !rpcChannel.isAlive()) {
364 rpcChannel = new AsyncRpcChannel(this.bootstrap, this, ticket,
serviceName, location);
355 connections.put(hashCode, rpcChannel);
{code}
A will attach patch in few minutes.
Table regions are not assigning back, after restarting all regionservers at

How does the ClusterConnection become stale? That should not happen. The whole
point is that the connection is stable even as machine in the cluster (or
indeed the entire cluster) have problems and are restarted.

Thanks for review [~stack],
As far as i can see we have two options for fixing this issue and handling
connection correctly:
1. Change default connection to non final and instead of creating new
connection object recreate existing connection in ServerManager#getRsAdmin(),
{code}
156- private final ClusterConnection connection;
156+ private ClusterConnection connection;
{code}
{code}
+ Configuration conf = master.getConfiguration();
+ this.connection = (ClusterConnection)
ConnectionFactory.createConnection(conf);
{code}
This connection will be closed when master is shutdown.
2. We can implement additional logic in ServerManager that will take care of
creating new connection when rs is restarted and close/remove it when becomes
staled.
I have tested first option and issue is fixed. Which method we prefer ?

Issue is directly related with changing rpc client implementation from
RpcClientImpl to AsyncRpcClient. I was testing master branch with RpcClientImpl
and issue is gone. Maybe we should check how we handle connection failures in
AsyncRpcClient.

*Steps to reproduce:*
1. Start HBase cluster with more than one regionserver.
2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*

*Steps to reproduce:*
1. Start HBase cluster with more than one regionserver.
2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.

I was able to find root cause of this issue it is in
ServerManager#getRsAdmin(), after regionserver is restarted {code}
ClusterConnection connection {code} becomes staled and need to be recreated in
order to master establish connection with restarted regionserver. Here is diff
of what i did in order to fix this issue:

I can confirm that this is still issue on master branch and here is what i have
concluded from testing (distributed cluster):
1. RS restart is enough to reproduce this issue.
2. As [~jxiang]] suggested this is not problem with AM. Issue is probably
related to RSRpcService on regionserver side.
3. I was able to trace this issue in case of assign operation to
(ServerManager.java):
{code}
734 public RegionOpeningState sendRegionOpen(final ServerName server,
HRegionInfo region, ListServerName favoredNodes)
{code}
master never gets response from regionserver because of
java.nio.channels.ClosedChannelException.
4. From logs i have notices that when RS is in this state
ServerManager#sendRegionWarmup is also failing with
java.nio.channels.ClosedChannelException.
5. When issue is present nothing about this requests is logged on RS side so my
assumption is that RPC server on rs side in some strange state.
I will try to dig some more info from rs side and post it here.

Jimmy Xiang commented on HBASE-13337:
-
I looked into it again and tried to reproduce it. Whenever a server is
restarted, we get lots of java.nio.channels.ClosedChannelException. This is
something new. So I tried with some old code, and found out there is no such
problem with the master branch commit 1723245282ba39567f7da4234cdd31ba534cb869
(Add in an hbasecon2015 logo for the banner).
This seems not to be a problem with assignment. I am not sure if branch-1 is
affected now.
It looks like this has something to do with the aysc RPC changes. Connections
seem not to be able to recover from server restarts.

I think this is graceful shutdown of the RSs, so log splitting would not come
into play... But the 2nd case could happen.

*Steps to reproduce:*
1. Start HBase cluster with more than one regionserver.
2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*

For graceful shutdown, no need for log splitting. Those regions on the dead
server are still re-assigned by SSH if the master is not restarted.

Wait, what's the issue? Looks like I have misunderstood. I read it as the
HMaster is not assigning the region back to the _original_ region server,
destroying data locality.
But you are saying no regions are assigned all, to any region server?
That'd definitely bad! And I agree with the blocker status then. [~jxiang],
wanna have a quick look?

*Steps to reproduce:*
1. Start HBase cluster with more than one regionserver.
2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*

-
Or master doesn't know it soon enough. It is a racing between SSH and master ZK
event handling (for regionserver is gone). Possible fixes could be (1) fail the
region assignments and re-queue the dead server for SSH, (2) fail the master
process (by shutting down itself) if such a scenario is detected.

Jimmy Xiang commented on HBASE-13337:
-
At step 4, all the region servers are down, master needs to split log and
recover those regions. In ServerShutdownHandler, we have
{noformat}
while (!this.server.isStopped()
serverManager.countOfRegionServers() 2) {
{noformat}
to wait till some regionserver joins in before assigning any region.
This looks like a racing issue. Although all regionservers are down, master
doesn't know it yet. So SSH starts to assign regions, which fails.

I think the same thing happens when there is one RS. When we stop and start
the RS we are not able to get any regions assigned.
Table regions are not assigning back, after restarting all regionservers at

*Steps to reproduce:*
1. Start HBase cluster with more than one regionserver.
2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*

All regionservers are restarted graceful,
I tested one more scenario like out of 3 regionservers make down one
regionserver graceful, in this case it is assigning properly.
All regionservers making down and startup again only causing problem.
Table regions are not assigning back, after restarting all regionservers at

Lars Hofhansl commented on HBASE-13337:

Right. But when all region servers are gone, HMaster cannot assign any regions.
As soon as the first few region servers are seen by the master again, it'll
assign all the regions to them.
In some case that might be what you want, in others it's not. Unless we tell
the master it can't know.
We can add some guessing of course. Maybe when more than 1/2 of the region
server are suddenly gone, wait a bit before reassigning the regions. But I will
bet that any guessing we do will have somebody complain.
Or we can invent a new API to tell the master to hold off assigning regions.
In the end the the solution is simple: If you plan to bring down many region
servers, stop the HMaster first.
Table regions are not assigning back, after restarting all regionservers at
once.

*Steps to reproduce:*
1. Start HBase cluster with more than one regionserver.
2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*

Mikhail Antonov commented on HBASE-13337:
-
Just to make sure I understood correctly - so when all RS's are restarted
simultaneously, HMaster decides not to assign to prevent re-assignment storm? I
thought in such situation master will start assignment as soon as restarted RSs
start checking back in, and in next minutes (or may be tens of minutes) the
regions would be reassigned?
Table regions are not assigning back, after restarting all regionservers at

correct [~ram_krish]
I verified the same scenario in HBase-0.98.11 version, there it is assigning
properly back to the newly restarted regionservers, and able to perform the
operations on those regions.
Table regions are not assigning back, after restarting all regionservers at

ramkrishna.s.vasudevan commented on HBASE-13337:
I think the intent here is that previously when such thing happen when all RS
were stopped, and again brought up the HMaster was in a position to assign
regions and not making the cluster hang. Same was the case with a single RS
set up also. The HMaster was able to assign once the RS was restarted. Now it
is not so.
Am i right about the intention of this issue [~sreenivasulu]?

*Steps to reproduce:*
1. Start HBase cluster with more than one regionserver.
2. Create a table with precreated regions. (lets say 15 regions)
3. Make sure the regions are well balanced.
4. Restart all the Regionservers process at once across the cluster, except
HMaster process
5. After restarting the Regionservers, successfully will connect to the
HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*

I thought we had fixed that a long time ago. I assume when you restarted the
cluster the default HMaster's wait fime (4.5s) is long enough for all former
region server to startup and sign-in?

On the other hand, what is the HMaster to do? When an RS dies we want to assign
its region as fast as possible. If you bring down all region servers by killing
the processes we have a fail fast logic that immediately reassigns the regions.
So when somebody plans to bring down all region server, the HMaster should be
brought down as well.

HMaster.
*Bug:*
But no regions are assigning back to the Regionservers.
*Master log shows as follows:*
