Subject [jira] [Commented] (ACCUMULO-1385) RPM/DEB should set vm.swappiness in /etc/sysctl.d/accumulo
Date Thu, 09 May 2013 15:01:24 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-1385?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13652999#comment-13652999
] 

Keith Turner commented on ACCUMULO-1385:
----------------------------------------

bq. An example of an RPM that does add its own modular config to /etc/sysctl.d

I did not even notice "/etc/sysctl.d/accumulo" in the summary.  Putting it in /etc/sysctl.d
resolves my concerns.

Following this line of thought, should we up nproc and nofile in /etc/security/limits.d? 
 It seems like adjustments to open file limits would need to apply to HDFS users more than
the accumulo user, so that may be tricky.
