What does the region server log say?
Endpoints do not run in a sandbox. You can call System.exit(...) and your
RegionServer will happily exit.
If you can, please show us your endpoint code.

Lars,
Thanks for your quick response.There is not much info in region server log. I
am again executing it with DEBUG log level in region servers.
Here is the endpoint code
public class ColumnAggregationEndpoint extends BaseEndpointCoprocessor
implements ColumnAggregationProtocol {
Lars,
It is having following errors when I execute the Endpoint RPC client from
eclipse. It seems some of the regions at regionserver
vm-8aa9-fe74.nam.nsroot.net is taking more time to reponse.
Could you guide how to fix it. I don't find any option to set hbase.rpc.timeout
from hbase
It seems to me that a major_compact table command from hbase shell do not fush
memstore? When I done with major compact, still some data in memstore and will
be flush out to disk when I shut down hbase cluster.
Best Regards,

We turned the block cache to false and tried again, regionserver still crash
one after another.
There are a lot of scanner lease time out, and then master log info:
RegionServer ephemeral node deleted, processing expiration
[rs21,60020,1363010589837]
Seems the problem is not caused by
How is the GC pattern in your RSs which are getting down? In RS logs you might
be having YouAreDeadExceptions...
Pls try tuning your RS memory and GC opts.

Guys,
thank you very much for the help.
Yesterday I spent 14 hours trying to tune the whole cluster.
The cluster is not ready yet needs a lot of tunning, but at least is
working.
My first big problem was namenode + datanode GC. They were not using
CMS and thus were taking incremental time to
how did you use scanner? paste some codes here.

Hi all,
Monitoring Hbase, we need to know the amount of bytes received by each region
server (and overall throughput).
The only metric I found for this is
RS.hadoop.service_HBase.name_RPCStatistics-60020.ReceivedBytes. However, this
metric
Is a delta and not total number. My question is is
I checked trunk code - parameter count matches.
Looks like this is a problem in 0.94 only

I don't see RS dying with this. It says that it is taking more time
than 60 sec (default timeout for clients), and therefore it stops
processing the coprocessor call as the client is disconnected.
Is your cluster okay? how many rows in the table? Normal scan works
good? Can you share more about
HBASE-8079 has been logged.

From region server log:

To expand on what Himanshu said, your endpoint is doing an unbounded scan
on the region, so with a region with a lot of rows it's taking more than 60
seconds to run to the region end, which is why the client side of the call
is timing out. In addition you're building up an in memory list of all

When I try to access HBase from a cluster node which is not the
zookeeper server I have the following problem:
-bash-3.2$ hostname
node33
-bash-3.2$ hbase shell
HBase Shell; enter 'helpRETURN' for list of supported commands.
Type exitRETURN to leave the HBase Shell

Hi Ryan,
Make sure you have the correct client configurations on the node you are
trying to access from. You will need the hbase-site and the zoo.cfg to
make this work.

Yes, I am having success with it.
We use Cloudera and there's a button, Generate Client Configuration,
which generated a .zip file with a very informative README.txt. The
trick is to extract that .zip and export HBASE_CONF_DIR :
hbase(main):002:0 exit
-bash-3.2$ hostname
node33
-bash-3.2$ export
I tried both hbase shell's major_compact cmd and java api
HBaseAdmin.majorCompact() on table name.
They don't flush the memstore on to disk, compact cmd seems not doing that too.
I hadn't read enough related code, While I am wondering, is that because there
are size threshold before a memstore
Raymond:
Major compaction does not first flush. Should it or should it be an option?

I am not sure what's the design idea behind it. While, If I want to
invoke a major compact manually, I guess what I want is that all separate file
and the memstore is combined into one file. If I don't write anything new
there, from the user point of view, I will assume that it
