Subject [jira] [Commented] (HADOOP-11764) Hadoop should have the option to use directory other than tmp for extracting and loading leveldbjni
Date Mon, 27 Apr 2015 23:52:39 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-11764?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14515869#comment-14515869
] 

Anubhav Dhoot commented on HADOOP-11764:
----------------------------------------

bq. In the past, we used hadoop.tmp.dir for stuff like this.
This use case of a tmpr is different than normal use cases of tmp directory as it is executing
code from there instead of treating as a directory for data. 

yes we can do it via *-env.sh or HADOOP_OPTS. The current solution was doing it via customizing
HADOOP_OPTS in a convenient way for the leveldb setting just like all other examples of "hadoop_add_param
HADOOP_OPTS" in hadoop-functions.sh. Would be good to document in the shell scripting guide
some conventions on when do we - a) document how to modify HADOOP_OPTS, or b) or add it to
*-env or c) create a new option - as essentially they all end up adding a System property
at the end of the day.

> /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.
