Assignee: Bharat Viswanadham
> Fix non-empty dir warning message when setting default EC policy
> ----------------------------------------------------------------
>
> Key: HDFS-13239
> URL: https://issues.apache.org/jira/browse/HDFS-13239
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Hanisha Koneru
> Assignee: Bharat Viswanadham
> Priority: Minor
>
> When EC policy is set on a non-empty directory, the following warning message
> is given:
> {code}
> $hdfs ec -setPolicy -policy RS-6-3-1024k -path /ec1
> Warning: setting erasure coding policy on a non-empty directory will not
> automatically convert existing files to RS-6-3-1024k
> {code}
> When we do not specify the -policy parameter when setting EC policy on a
> directory, it takes the default EC policy. Setting default EC policy in this
> way on a non-empty directory gives the following warning message:
> {code}
> $hdfs ec -setPolicy -path /ec2
> Warning: setting erasure coding policy on a non-empty directory will not
> automatically convert existing files to null
> {code}
> Notice that the warning message in the 2nd case has the ecPolicy name shown
> as null. We should instead give the default EC policy name in this message.
