Subject [jira] Updated: (MAPREDUCE-1403) Save file-sizes of each of the artifacts in DistributedCache in the JobConf
Date Tue, 16 Feb 2010 07:34:28 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1403?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Hemanth Yamijala updated MAPREDUCE-1403:
----------------------------------------

    Release Note: Added private configuration variables: mapred.cache.files.filesizes and
mapred.cache.archives.filesizes to store sizes of distributed cache artifacts per job. This
can be used by tools like Gridmix in simulation runs.

> It would be a useful metric to collect... potentially GridMix could use it to emulate
jobs which use the DistributedCache.
