Hi,
I want to know the performance of hbase on doing updation operation.
How good is Hbase on Updation ?
Please suggest.
Thanks in advance.

Yes, I'm using metrics2 with ganglia.
And I have closed ganglia, because there is too many region metrics.
But I don't delete metrics2 configuration in
$HBASE_HOME/conf/hadoop-metrics2-hbase.properties. Is this OK?
Thanks

hi,
i am using hbase 0.94.10, Distribution: Apache
i am working on jruby scripts to create custom hbase command.
I want to know whether I can create a custom hbase command similar to
already available scan, put commands.. I have a sample jruby script,
client.rb that outputs the Row ID and Value
bcc : user@
cc : dev@
During startup shell loads the commands from shell/commands/* [1] and calls
appropriate command when invoked [2].

I was waiting for Matt Corgan to take a look at prefix tree changes in the fix
for HBASE-11234.

Which hbase release are you considering ?
Different releases have different implementation for the write path. E.g., 0.98
release has HBASE-8755. In trunk, disruptor is introduced.
This means write performance gets faster with each major release.

Can you pastebin the contents of conf/hadoop-metrics2-hbase.properties ?
Thanks

HBASE-11253 also can be fixed in next RC. Patch is available in Jira. Pls
review.

hi,
HBase version is 0.96.
Occasionally, a large cluster got the time out(stacktrace at the end of the
email) when access UI or Hbase shell. HBase Master seems working fine as a
load job was running and eventually completed successfully.
I did some google and found a suggestion to increase
Hello Demai,
Have you seen any thing else going on the master, e.g. high cpu load? Can
you try to get a jstack of the HBase master next time you experience this
issue? Also how many regions you have in this cluster and how many RPC
handlers have you configured for the master?
regards,
esteban.
Then it may not get in.

The fix for 11251 has introduced a new problem as reported on the JIRA. I can
fix it with an addendum. If there are more commits of ready to go patches in
the meantime we can add them to the next RC. Otherwise the train is leaving.

hi, Esteban,
thanks for the quick response.
We have a load job running at the time, I believe the task was both high
CPU and IO, and may cause some hotspot. Well, it wasn't my cluster, so I
don't have the first hand info. But from the past experience, we may have
one hot regionServer with quite
New RC forthcoming

A few things pop out to me on cursory glance:
- You are using CMSIncrementalMode which after a long chain of events has a
tendency to result in the famous Juliet pause of death. Can you try Par New GC
instead and see if that helps?
- You should try to reduce the CMSInitiatingOccupancyFraction to
@Flavio:
One thing you should consider: is CPU over saturated?
For instance, if one server has 24 cores, and the task tracker is configured to
also execute 24 MR simultaneously, then there is no core left for HBase to do
GC, and then crash.
Few weeks ago my region server sometimes crash when
