offline?)

> URL: https://issues.apache.org/jira/browse/CASSANDRA-13624
> Project: Cassandra
> Issue Type: Bug
> Reporter: Robin Mahony
>
> CASSANDRA-7953 can lead to range tombstones not properly being compacted.
> When trying to upgrade from Cassandra 2.0.X to 2.1.X, running upgradesstables
> (either via nodetool OR the offline version) does not work, as it crashes
> with OOM. This essentially means if you are running a version of Cassandra
> 2.0.X for a period of time where lots of range tombstones have been
> generated; you will be unable to upgrade to Cassandra 2.1.X following the
> normal procedures. Hence upgrade from 2.0.X to 2.1.X is essentially broken if
> you hit CASSANDRA-7953.
> I hit this while trying to upgrade to Cassandra 2.1.17.
> Offline Version:
> # sstableupgrade storagegrid s3_usage_delta
> Found 15 sstables that need upgrading.
> Upgrading
> SSTableReader(path='/var/local/cassandra/data/0/storagegrid/s3_usage_delta/storagegrid-s3_usage_delta-jb-20230-Data.db')
