Subject [jira] [Commented] (HBASE-13153) Bulk Loaded HFile Replication
Date Tue, 30 Jan 2018 05:07:02 GMT

    [ https://issues.apache.org/jira/browse/HBASE-13153?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16344508#comment-16344508

Anoop Sam John commented on HBASE-13153:
----------------------------------------

This feature as such is not described in book? If so, we have to add.  Ya we have to update
the section with removing the replication related limitation.
Many bugs were resolved in bulk load and all such fix should be there in 1.3+ versions. The
mentioned potential issues also seems out of date.

> Currently we plan to use HBase Replication feature to deal with disaster tolerance scenario.But
we encounter an issue that we will use bulkload very frequently,because bulkload bypass write
path, and will not generate WAL, so the data will not be replicated to backup cluster. It's
inappropriate to bukload twice both on active cluster and backup cluster. So i advise do some
modification to bulkload feature to enable bukload to both active cluster and backup cluster
