Aniket Mokashi commented on PIG-2672: ------------------------------------- I realized this fix won't work with Hadoop 2 (at least easily). Let me try to do some shims to fix it. Meantime, please comment on the approach. > Optimize the use of DistributedCache > ------------------------------------ > > Key: PIG-2672 > URL: https://issues.apache.org/jira/browse/PIG-2672 > Project: Pig > Issue Type: Improvement > Reporter: Rohini Palaniswamy > Fix For: 0.13.0 > > Attachments: PIG-2672-5.patch, PIG-2672.patch > > > Pig currently copies jar files to a temporary location in hdfs and then adds > them to DistributedCache for each job launched. This is inefficient in terms > of > * Space - The jars are distributed to task trackers for every job taking > up lot of local temporary space in tasktrackers. > * Performance - The jar distribution impacts the job launch time. -- This message was sent by Atlassian JIRA (v6.1.5#6160)
