Richard Hesse commented on CASSANDRA-16764:
-------------------------------------------
It was a good try, but no joy. We're getting the original heap error, but this
time on the splitting side:
{noformat}
$ sstablesplit --size 1700 --no-snapshot md-5357-big-Data.db
WARN 17:55:50 Live sstable {REDACTED}/md-5357-big-Data.db from level 3 is not
on corresponding level in the leveled manifest. This is not a problem per se,
but may indicate an orphaned sstable due to a failed compaction not cleaned up
properly.

Going back to my scrub comment from earlier, it might be worth considering. If
Cassandra can't compact or split the data, it's probably worth considering that
data corrupt from an operational standpoint.
