Subject [jira] [Commented] (HBASE-18448) Added support for refreshing HFiles through API and shell
Date Fri, 28 Jul 2017 04:30:03 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16104434#comment-16104434

ramkrishna.s.vasudevan commented on HBASE-18448:
------------------------------------------------

And one more thing,
HBase with read replica support already has this feature of refreshing the store files on
the secondary when ever a flush/compaciton happens on the primary. You may want to look at
it also(in case you have not) . JFYI.

> In the case where multiple HBase clusters are sharing a common rootDir, even after flushing
the data from
> one cluster doesn't mean that other clusters (replicas) will automatically pick the new
HFile. Through this patch,
> we are exposing the refresh HFiles API which when issued from a replica will update the
in-memory file handle list
> with the newly added file.
> This allows replicas to be consistent with the data written through the primary cluster.
