Jonathan Hsieh commented on HBASE-7523:
---------------------------------------
The core of this patch fixes a list removal bug that blocked a snapshot with
the same name as a preivous snapshot to fail occasionally (it wasn't GC'ed
before attempted again). This bug was introduced when we switched to guava's
mapmaker. (an earlier rev had a custom map like structure that had slightly
different behavior).
This patch also has a handful of typo fixes and logging improvements that were
useful in hunting this down.
> Snapshot attempt with the name of a previously taken snapshots fails
> sometimes.

> In a test rig, we repeatedly snapshot, clone and delete a table with the same
> using the same set of snapshot names. Sometimes, the snapshot request will
> be rejected until the hmaster is restarted.
