Subject [jira] Commented: (HADOOP-2867) Add a task's cwd to it's LD_LIBRARY_PATH
Date Tue, 20 May 2008 20:14:55 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12598444#action_12598444
] 

Christian Kunz commented on HADOOP-2867:
----------------------------------------

I only asked for pre-configuring LD_LIBRARY_PATH by the framework for the convenience of the
application programmer not to have to write a wrapper when the executable needs some shared
libraries not already deployed on the nodes.
No big deal.

> HADOOP-1660 added the task's cwd to it's java.library.path which means only java task's
can take advantage via System.load or System.loadLibrary... we should enhance it to support
Hadoop Pipes applications by adding it to the LD_LIBRARY_PATH so they can use dlopen/dlsym
etc.
