> 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
> 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
