Yuki Morishita commented on CASSANDRA-11693:
--------------------------------------------
I haven't reproduced this in local yet, but from the log files attached, I
figured out what's going on.
I think the failure is happening when C* flushes table to range-aware JBOD and
one of them end up 0 bytes (so no SSTable created on that disk).
{code}
DEBUG [PerDiskMemtableFlushWriter_2:1] 2016-05-24 11:03:20,528
Memtable.java:447 - Completed flushing
/mnt/tmp/dtest-7b4ZHQ/test/node1/data2/ks/users-1f027430219f11e6944229accea9bb00/mb-3-big-Data.db
(0.000KiB) for commitlog position ReplayPosition(segmentId=1464087795410,
position=50933)
{code}
After this, internal SSTable counter is incremented to 4, and scrub will
produce SSTable 4 and 5. However, there are only 1 and 2 SSTables before scrub,
the test expects SSTables 3 and 4 will be present after scrub by incrementing
current SSTable file's generation from file name
({{increase_sstable_generations()}}).
I'm still trying to figure out how to fix test, but since currently there is no
way to get what the next SSTable generation will be, assinging tokens to the
node manually so there won't be zero byte SSTable created to the disk.
