Dick King commented on MAPREDUCE-1641: -------------------------------------- Should {{mapred.cache.libjars}} be checked too? > Job submission should fail if same uri is added for mapred.cache.files and > mapred.cache.archives > ------------------------------------------------------------------------------------------------ > > Key: MAPREDUCE-1641 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1641 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: distributed-cache > Reporter: Amareshwari Sriramadasu > Assignee: Dick King > Fix For: 0.22.0 > > Attachments: BZ-3539321--off-0-20-101--2010-04-20.patch, > duped-files-archives--off-0-20-101--2010-04-21.patch, > duped-files-archives--off-0-20-101--2010-04-23--1819.patch, > mapreduce-1641--2010-04-27.patch, patch-1641-ydist-bugfix.txt > > > The behavior of mapred.cache.files and mapred.cache.archives is different > during localization in the following way: > If a jar file is added to mapred.cache.files, it will be localized under > TaskTracker under a unique path. > If a jar file is added to mapred.cache.archives, it will be localized under a > unique path in a directory named the jar file name, and will be unarchived > under the same directory. > If same jar file is passed for both the configurations, the behavior > undefined. Thus the job submission should fail. > Currently, since distributed cache processes files before archives, the jar > file will be just localized and not unarchived. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
