Subject Running an jython import job
Date Fri, 23 Jul 2010 16:58:34 GMT
Hello all,

I am running a job from jython that is importing time series data into HBase.  I started to
see the following messages and wanted to dive deeper to find out if they are true errors or
just debug messages:

10/07/23 09:51:07 DEBUG client.HConnectionManager$TableServers: Reloading region subset,a40506-2016/07/23-20:33:30.296,1279902520534
location because regionserver didn't accept updates; tries=0 of max=10, waiting=1000ms
10/07/23 09:51:08 DEBUG client.HConnectionManager$TableServers: Cached location for .META.,,1
is 10.10.11.3:60020
10/07/23 09:51:08 DEBUG client.HConnectionManager$TableServers: locateRegionInMeta attempt
0 of 10 failed; retrying after sleep of 1000 because: No server address listed in .META. for
region subset,a40506-2016/07/24-07:00:35.528,1279903897169
10/07/23 09:51:09 DEBUG client.HConnectionManager$TableServers: Cached location for subset,a40506-2016/07/24-07:00:35.528,1279903897169
is 10.10.11.2:60020

I did some searches on google and this seems to point at the potential lack of memory.  Currently,
HBase is setup with a heap of 2G for each slave, and there are 6 slaves.  Each slave has a
total of 8G of RAM installed.  If you guys have any guidance on what other settings I should
look for, please let me know.

Thanks!
