> Project: Hadoop HDFS
> Issue Type: Sub-task
> Affects Versions: HDFS-7285
> Reporter: Vinayakumar B
> Assignee: Vinayakumar B
> Fix For: HDFS-7285

> In HDFS-7285 branch,
> To determine whether file is striped/not and get the Schema for the file, 2
> RPCs done to Namenode.
> This is resulting in double audit logs for every file read for both
> striped/non-striped.
> This will be a major impact in size of audit logs.
