Subject [jira] [Commented] (INFRA-3734) Building hbase we run into 'too many files'; can we up the ulimit > 1024?

    [ https://issues.apache.org/jira/browse/INFRA-3734?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13060917#comment-13060917

Tony Stevenson commented on INFRA-3734:
---------------------------------------

I have fixed Vesta now.  

bash-3.2$ ssh pctony@vesta.apache.org "ulimit -n"
40000

It seems that ssh was restarted with   'service ssh {restart, stop, start}'  This has two
issues, 

1- it doesnt use the init script, and thus ignores the setting.  If you tried restarting sshd
with the init script, it would have no effect as sshd was started using the service tool.

2- sshd was started with a -D flag, basically dont daemonize.  So I had to kill sshd, and
start it with the init script.

> Buliding on hudson we'll run into 'too many files' issues when running some of our more
intense tests (Yes, hbase is an fd hog): see https://builds.apache.org/view/G-L/view/HBase/job/hbase-0.90/215/artifact/trunk/target/surefire-reports/org.apache.hadoop.hbase.client.TestFromClientSide.txt
for an example.  I tried upping fds for the the build process by having jenkins execute some
shell before the maven build cuts in but this failed -- its not allowed apparently.
> Any chance of having the jenkins user's fds upped?  By 10x?
> Thanks.
