Subject [jira] [Commented] (HADOOP-9426) Hadoop should expose Jar location utilities on its public API
Date Tue, 26 Mar 2013 00:41:16 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-9426?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13613348#comment-13613348
] 

Enis Soztutar commented on HADOOP-9426:
---------------------------------------

bq. You don't need to use uber-jars, you can use -libjars to push jars to the cluster and
have them in the classpath together with your job.
Yes, but you have to be able to find the jars which the jar finder does. We combine this with
"tmpjars" to ship the jars currently. Not all jobs are invoked from command line.

> The facilities behind JobConf#setJarByClass and the JarFinder utility in test are both
generally useful. As the core platform, these should be published as part of the public API.
In addition to HBase, they are probably useful for Pig and Hive as well. See also HBASE-2588,
HBASE-5317, HBASE-8140.
