Subject [jira] [Commented] (HBASE-18448) Added support for refreshing HFiles through API and shell
Date Mon, 31 Jul 2017 04:22:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-18448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16106793#comment-16106793
] 

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

bq.My only concern here is that we are already exposing this as an API.
Yes as I said in my previous comment as this is exposed in shell you may have to provide CP
endpoint way and also the old way until you find ways to remove the API support.

> 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.
