Nevermind, I see it now.

> 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.
