Subject [jira] [Commented] (YARN-3331) NodeManager should use directory other than tmp for extracting and loading leveldbjni
Date Tue, 24 Mar 2015 20:39:54 GMT

    [ https://issues.apache.org/jira/browse/YARN-3331?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14378556#comment-14378556

Anubhav Dhoot commented on YARN-3331:
-------------------------------------

I am not sure which value in core-site would fix this after going through the core-default
documentation. The only way i can think about is using the appropriate environment variable
for eg setting the YARN_NODEMANAGER_OPTS value for Nodemanager

> /tmp can be  required to be noexec in many environments. This causes a problem when 
nodemanager tries to load the leveldbjni library which can get unpacked and executed from
/tmp.
