Subject [jira] Commented: (HADOOP-2867) Add a task's cwd to it's LD_LIBRARY_PATH
Date Mon, 19 May 2008 09:03:56 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-2867?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12597898#action_12597898

Amareshwari Sriramadasu commented on HADOOP-2867:

bq. The -program option in pipes command line allows to add files beyond the executable (comma
separated) and they will all end up in the local cache.

The -program option in pipes is expected to take only executable URI. Comma separated files
ending up in local cache looks like a hack. Should this be supported? Either we support or
not, I think this needs to be documented.

bq. it would be nice if the task could be configured to add all parent directories of mapred.cache.localFiles
Christian, do you mean the immediate parents of all mapred.cache.localFiles or the whole parent
hierarchy of mapred.cache.localFiles?

> 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
