I have tested this manually and verified that it works > HAR files used for RAID parity need to have configurable partfile size > ---------------------------------------------------------------------- > > Key: MAPREDUCE-1816 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-1816 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Components: contrib/raid > Affects Versions: 0.20.1 > Reporter: Ramkumar Vadali > Assignee: Ramkumar Vadali > Priority: Minor > Fix For: 0.22.0 > > Attachments: MAPREDUCE-1816.patch, MAPREDUCE-1816.patch.1 > > > RAID parity files are merged into HAR archives periodically. This is required > to reduce the number of files that the NameNode has to track. The number of > files present in a HAR archive depends on the size of HAR part files - higher > the size, lower the number of files. > The size of HAR part files is configurable through the setting > har.partfile.size, but that is a global setting. This task introduces a new > setting specific to raid.har.partfile.size, that is used in-turn to set > har.partfile.size -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
