> Avoid allocation of CorruptedBlocks hashmap when no corrupted blocks are hit
> ----------------------------------------------------------------------------
>
> Key: HDFS-13703
> URL: https://issues.apache.org/jira/browse/HDFS-13703
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: performance
> Reporter: Todd Lipcon
> Assignee: Todd Lipcon
> Priority: Major
> Attachments: hdfs-13703.patch
>
>
> The DFSClient creates a CorruptedBlocks object, which contains a HashMap, on
> every read call. In most cases, a read will not hit any corrupted blocks, and
> this hashmap is not used. It seems the JIT isn't smart enough to eliminate
> this allocation. We would be better off avoiding it and only allocating in
> the rare case when a corrupt block is hit.
> Removing this allocation reduced CPU usage of a TeraValidate job by about 10%.
