Subject: HBase establishes session with ZooKeeper and close the session

I have found that our RegionServers connect to the ZooKeeper
I have seen the similar log in someone's blog and it's based on 0.94.20.
The CatalogTracker seems to be initialized for many times.

I have found that our RegionServers connect to the ZooKeeper frequently.
They seems to constantly establish the session, close it and reconnect the
ZooKeeper. Here is the log for both server and client sides. I have no idea
why this happens and how to deal with it? We're using HBase 0.94.11 and

Looks like curl doesn't interpret the redirection.

It's a little wired when I ran the standalone HBase cluster from trunk. I
notice that the default RegionServer info port is not 16010.
And when I explicitly set hbase.regionserver.info.port, it doesn't work. It
changes every time I run.
and it doesn't have this problem.

If you're running trunk build, from HConstants.java :

Hi tobe,
yes we are replicating during verify.
So as I understand, the problem is that during the verify job the one key
is updated (with new timestamp)
while this key will be verified. So on one side the key timestamp is in
the verify timerange but on the
other side
It's the bug of VerifyReplication, please refer to [HBASE-10153]

Need someone to review and fix it.

optimizations around this: we skip reading early if the
timestamps of what we're reading is not in the scan range. So we don't know
if there is a newer value.
What's the use case you're looking at?

Thanks @nicolas, @andrew and @lars. The problem like this always comes
down to by design. It depends on the semantic that HBase provides.
As a user, I don't expect different results when I sent the same request

We have deployed a large HBase cluster in our production environment.
Sometimes a few region servers crash and we have supervisord to bring them
up. Occasionally it shows address always in use because the operation
system doesn't release the port immediately.
Recently I read something about
So far, I have found two problems about this.
Firstly, HBase-11675 https://issues.apache.org/jira/browse/HBASE-11675.
It's a little tricky and rarely happens. But it asks users to be careful of
compaction which occurs on server side. They may get different results
before and after the major

Sometimes our users want to upgrade their servers or move to a new
datacenter, then we have to migrate the data from HBase. Currently we
enable the replication from the old cluster to the new cluster, and run
CopyTable to move the older data.
It's a little inefficient. It takes more than one day
such that
they sort in the same order as the HBase key. Then read through those
results and the HBase scan at the same time, advancing both sides together.
That way you need only a single scan on both sides (per table).

@Ravi Do you mean using a key + timestamp as rowkey in HBase shell?
If so, you can `import java.text.SimpleDateFormat` to get the timestamp.
