Dmitriy V. Ryaboy commented on PIG-2318: ---------------------------------------- Looks good to me, +1. I suppose we are supposed to test this sort of thing using the e2e framework? Alan? > Push extra jars to distributed cache and use the classloader enxtension > mechanism in PigContext to load them on the backend > --------------------------------------------------------------------------------------------------------------------------- > > Key: PIG-2318 > URL: https://issues.apache.org/jira/browse/PIG-2318 > Project: Pig > Issue Type: Improvement > Components: impl > Reporter: Julien Le Dem > Assignee: Julien Le Dem > Attachments: PIG-2318.patch, PIG-2318_2.patch > > > This is related to PIG-2010 with a slightly different approach > https://issues.apache.org/jira/browse/PIG-2010 > Currently Pig bundles up all dependencies in a single jar which is a lot of > overhead when there are a lot of dependencies and short lived jobs. 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.
