Subject Re: way to add custom udf jar in hadoop 2.x version
Date Wed, 31 Dec 2014 08:53:23 GMT
I found that the easiest way is to put udf  jar to /usr/lib/hadoop-mapred
on all computers in the cluster. Hive cli, hiveserver2, oozie launcher,
oozie hive action, mr will see the jar then. I'm using hdp-2.1.5
