Subject [jira] [Commented] (HDFS-11163) Mover should move the file blocks to default storage once policy is unset
Date Mon, 10 Apr 2017 21:25:41 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11163?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15963498#comment-15963498

Chris Nauroth commented on HDFS-11163:
--------------------------------------

[~surendrasingh], sorry, but the patches need to be rebased again.  Sorry for the churn. 
I'll do my best to prioritize getting these committed right after you post new patches so
that you don't have to rebase again.

> HDFS-9534 added new API in FileSystem to unset the storage policy. Once policy is unset
blocks should move back to the default storage policy.
> Currently mover is not moving file blocks which have zero storage ID
> {code}
>       // currently we ignore files with unspecified storage policy
>       if (policyId == HdfsConstants.BLOCK_STORAGE_POLICY_ID_UNSPECIFIED) {
>         return;
>       }
> {code}
