Alex Petrov commented on CASSANDRA-10962:
-----------------------------------------
true, my initial patch was to add {{skipSnapshot}}, although logic there was
getting tricky, so I simplified it.
Just to give heads up, in 3.0+ this problem does not appear as
[~fabrice.facorat] mentioned due to
[7066|https://issues.apache.org/jira/browse/CASSANDRA-7066].
I've checked the failing dtests locally, both are passing. With unit tests,
it's same. Same with utests...

> Cassandra should not create snapshot at restart for compactions_in_progress
> ---------------------------------------------------------------------------

> Key: CASSANDRA-10962
> URL: https://issues.apache.org/jira/browse/CASSANDRA-10962
> Project: Cassandra
> Issue Type: Bug
> Environment: Ubuntu 14.04.3 LTS
> Reporter: FACORAT
> Assignee: Alex Petrov
> Priority: Minor
> Fix For: 2.2.x
>
>
> If auto_snapshot is set to true in cassandra.yaml, each time you restart
> Cassandra, a snapshot is created for system.compactions_in_progress as the
> table is truncated at cassandra start.
> However as datas in this table are temporary, Cassandra should not create
> snapshot for this table (or maybe even for system.* tables). This will be
> coherent with the fact that "nodetool listsnapshots" doesn't even list this
> table.
> Exemple:
> {code}
> $ nodetool listsnapshots | grep compactions
> $ ls -lh
> system/compactions_in_progress-55080ab05d9c388690a4acb25fe1f77b/snapshots/
