[jira] [Commented] (HBASE-21415) Admin#snapshot method
documentation is misleading.
[ https://issues.apache.org/jira/browse/HBASE-21415?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16853858#comment-16853858 ]
Josh Elser commented on HBASE-21415:
------------------------------------
[~gsbiju] or [~plaflamme], can either of you glance at my modified patch? Should be an improvement, but want to make sure I didn't miss anything else obvious :).
Backporting this will probably require unique patches. Maybe [~dbist13] would want to help with that leg-work?

> The documentation for the {{Admin#snapshot}} function is misleading in regards to snapshot concurrency.
> It currently states the following:
> {quote}Only a single snapshot should be taken at a time for an instance of HBase, or results may be undefined (you can tell multiple HBase clusters to snapshot at the same time, but only one at a time for a single cluster).
> {quote}
> This seems to indicate that it's dangerous to run snapshots concurrently when in fact the HBase master will simply run them sequentially (as per this Slack thread [https://apache-hbase.slack.com/archives/C13K8NVAM/p1540994948005900)]
> The suggested fix is to simply remove this entire sentence.
