When trying to repair full on a table with the following schema my nodes stall
and end up with spamming this
I've recently changed the table from SizeTieredCompactionStrategy to LeveledCompactionStrategy.
Coming from 2.1.9 -> 2.2.0 -> 2.2.1 i ran upgradesstable without issue as well
When trying to full repair post compaction change, I got "out of order" errors. A few google searches later, I was told to "scrub" the keyspace - did that during the night (no problems logged, and no data lost)
Now a repair just stalls and output memory leaks all over the place
{code}
CREATE KEYSPACE sessions WITH replication = {'class': 'SimpleStrategy', 'replication_factor': '3'} AND durable_writes = true;
CREATE TABLE sessions.sessions (

) WITH bloom_filter_fp_chance = 0.01
AND caching = '{"keys":"NONE", "rows_per_partition":"NONE"}'
