This > patch instead pushes the dependencies to distributed cache and uses the > PigContext classloading mechanism to make the UDFs available. > Possible improvements: push jars to HDFS/distributed cache only once per > script. have a cache on HDFS to avoid repeatedly pushing jars to HDFS. -- This message is automatically generated by JIRA.
