Philippe Laflamme commented on HBASE-21415:
-------------------------------------------
[~elserj] noticed one problem with one of the comments. One of them is missing
a period:
{quote}sequentially even when requested concurrentlySnapshots are considered
unique{quote}
Also, when it says
{quote}Snapshots are taken sequentially even when requested concurrently.{quote}
I would specify whether this is per table or globally (not sure which one it
is). e.g.
if it's per table:
{quote}Snapshots are taken sequentially even when requested concurrently, per
table.{quote}
or if it's globally:
{quote}Snapshots are taken sequentially even when requested concurrently,
across all tables.{quote}
> Admin#snapshot method documentation is misleading.

> 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.
