> Use HAR filesystem to merge parity files
> -----------------------------------------

> Key: HDFS-684
> URL: https://issues.apache.org/jira/browse/HDFS-684
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: contrib/raid
> Reporter: dhruba borthakur
> Assignee: Rodrigo Schmidt
> Attachments: HDFS-684.0.patch, HDFS-684.1.patch
>
>
> The HDFS raid implementation (HDFS-503) creates a parity file for every file
> that is RAIDed. This puts additional burden on the memory requirements of the
> namenode. It will be nice if the parity files are combined together using
> the HadoopArchive (har) format.
