Hi,
I was running coprocessor AggregationProtocol, it got socket
timeout exception. Somebody said to set hbase.rpc.timeout to larger
value.
I added the following in hbase.site.xml
property
namehbase.rpc.timeout/name
value300/value
/property
but it was not working. The
Thanks for the responses. I am using 0.90.4-cdh3. i exported the table
using hbase exporter. Yes, the previous table still exists but on a
different cluster.My region servers are large, close to 12GB in size.
I want to understand regarding Hfiles. We export the table as a series of
Hfiles and
You must rewrite you own ruby script to support command like max, min
after deploy your endpoint.

Which is the total number of your regions?

Mind posting some regionserver logs while its under load?
Attached. This is while running 100 threads making autoFlushed writes.
The throughput on this regionserver is about 1000 wps
They did not come across Juhani.
The timeout is on the client side, not the server side.

This is a client-side configuration so if your mapred-site.xml is
_not_ on your classpath when you start the bulk load, it's not going
to pick it up. So either have that file on your classpath, or put it
in whatever other configuration file you have.

Well that's not an HBase configuration, that's Hadoop. I'm not sure if
this is listed anywhere, maybe in the book.
BTW usually HBase has a client somewhere in the same to indicate
it's client side.

Speculative execution is on by default in Hadoop. One of the Performance
recommendations in the Hbase RefGuide is to turn it off.

Hi Doug,
Yes, that's why i had set that property as false in my mapred-site.xml.
But, to my surprise i didnt know that setting that property would be
useless for Hadoop jobs unless the mapred-site.xml is in classpath. The
idea of client side property is a little confusing to me at present since

Can you please attach the RS logs from the failure?

Hi Kevin,
Here is dropbox link to the log file of region server which failed:

IMHO, the problem starts from the line #3009 which says: 12/03/30 15:38:32

Anil,
You can also disable speculative execution on a per-job basis. See
http://hadoop.apache.org/common/docs/current/api/org/apache/hadoop/mapreduce/Job.html#setMapSpeculativeExecution(boolean)
(Which is why it is called a client-sided property - it applies
per-job).
