> Memory footprint optimization for INodeFile object.
> ----------------------------------------------------
>
> Key: HDFS-1061
> URL: https://issues.apache.org/jira/browse/HDFS-1061
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: name-node
> Affects Versions: 0.22.0
> Reporter: Bharath Mundlapudi
> Assignee: Bharath Mundlapudi
> Priority: Minor
> Fix For: 0.22.0
>
> Attachments: HDFS-1061-1.patch, HDFS-1061.patch
>
>
> I am proposing a footprint optimization to merge blockReplication and
> preferredBlockSize fields into one 'long header' field in INodeFile class.
> This saves 8 bytes per INodeFile object on a 64 bit JVM. This memory
> optimization is transparent and changes are very minimal.
