Consider a case where my master is getting restarted. RS that was alive when
the master restart started, gets restarted before the master initializes the
ServerShutDownHandler.
{code}
serverShutdownHandlerEnabled = true;
{code}
In this case when the RS tries to register with the master, the master will
try to expire the server but the server cannot be expired as still the
serverShutdownHandler is not enabled.
This case may happen when i have only one RS gets restarted or all the RS
gets restarted at the same time.(before assignRootandMeta).
{code}
LOG.info(message);
if (existingServer.getStartcode() serverName.getStartcode()) {
LOG.info(Triggering server recovery; existingServer +
existingServer + looks stale, new server: + serverName);
expireServer(existingServer);
}
{code}
If another RS is brought up then the cluster comes back to normalcy.
May be a very corner case.

RS restart just before master intialization we make the cluster non operative
-
Key: HBASE-5916
URL: https://issues.apache.org/jira/browse/HBASE-5916
Project: HBase
Issue Type: Bug
Affects Versions: 0.92.1, 0.94.0
Reporter: ramkrishna.s.vasudevan
Assignee: ramkrishna.s.vasudevan
Priority: Critical
Fix For: 0.94.1
Attachments: HBASE-5916_trunk.patch, HBASE-5916_trunk_1.patch,
HBASE-5916_trunk_1.patch, HBASE-5916_trunk_2.patch, HBASE-5916_trunk_3.patch,

Consider a case where my master is getting restarted. RS that was alive when
the master restart started, gets restarted before the master initializes the
ServerShutDownHandler.
{code}
serverShutdownHandlerEnabled = true;
{code}
In this case when the RS tries to register with the master, the master will
try to expire the server but the server cannot be expired as still the
serverShutdownHandler is not enabled.
This case may happen when i have only one RS gets restarted or all the RS
gets restarted at the same time.(before assignRootandMeta).
{code}
LOG.info(message);
if (existingServer.getStartcode() serverName.getStartcode()) {
LOG.info(Triggering server recovery; existingServer +
existingServer + looks stale, new server: + serverName);
expireServer(existingServer);
}
{code}
If another RS is brought up then the cluster comes back to normalcy.
May be a very corner case.

Project: HBase
Issue Type: Bug
Affects Versions: 0.92.1, 0.94.0
Reporter: ramkrishna.s.vasudevan

Consider a case where my master is getting restarted. RS that was alive when
the master restart started, gets restarted before the master initializes the
ServerShutDownHandler.
{code}
serverShutdownHandlerEnabled = true;
{code}
In this case when the RS tries to register with the master, the master will
try to expire the server but the server cannot be expired as still the
serverShutdownHandler is not enabled.
This case may happen when i have only one RS gets restarted or all the RS
gets restarted at the same time.(before assignRootandMeta).
{code}
LOG.info(message);
if (existingServer.getStartcode() serverName.getStartcode()) {
LOG.info(Triggering server recovery; existingServer +
existingServer + looks stale, new server: + serverName);
expireServer(existingServer);
}
{code}
If another RS is brought up then the cluster comes back to normalcy.
May be a very corner case.

The patch still applies correctly in Windows thro SVN client. But finally its

Tried to address this problem using the system time. The test case attached in
the patch reproduces the issue of how the HLog gets deleted.
If the way of using time to avoid this issue seems bad pls don't Hate me. I
think atleast the test case will be useful.
I tried to use the zk but the problem is we will not be sure if that server is
about to be expired server or current new server.

If another RS is brought up then the cluster comes back to normalcy.
May be a very corner case.
was:
Consider a case where my master is getting restarted. RS that was alive when
the master restart started, gets restarted before the master initializes the
ServerShutDownHandler.
{code}
serverShutdownHandlerEnabled = true;
{code}
In this case when the RS tries to register with the master, the master will try
to expire the server but the server cannot be expired as still the
serverShutdownHandler is not enabled.
This case may happen when i have only one RS gets restarted or all the RS gets
restarted at the same time.(before assignRootandMeta).
{code}
{code}
RS restart just before master intialization we make the cluster non operative

[jira] [Updated] (HBASE-5916) RS restart just before master intialization we make the cluster non operative
[
https://issues.apache.org/jira/browse/HBASE-5916?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]
ramkrishna.s.vasudevan updated HBASE-5916:

Priority: Critical (was: Major)
Upped the priority of this defect. While master is coming up
{code}
1-Wait for region server to register
2-Get the online server list
3- Start splitting the logs
{code}
Between step 2 and 3 if another new region server registers, we just split the
logs of the new region server and in fact delete the HLog folder for that new
region server. This seems critical.
While analysing the issue for which this JIRA was created we ended up in this
problem.
