> URL: https://issues.apache.org/jira/browse/HBASE-20101
> Project: HBase
> Issue Type: New Feature
> Reporter: Jean-Marc Spaggiari
> Assignee: huaxiang sun
> Priority: Major
>
> HDFS blocks can move for many reasons. HDFS balancing, lost of a disk, of a
> node, etc. However, today, locality seems to be calculated when the files are
> opened for the first time. Even disabling and re-enabling the regions doesn't
> trigger a re-calculation of the locality.
> We should provide a way to let the user ask for this number to be
> re-calculated.
