Description
Master is stuck for two days trying to rejoin cluster after monkey killed and restarted it.
After retrying to get namespace 350 times, Master goes down:

Seems like 2014-12-20 16:49:03,665 INFO [RS_LOG_REPLAY_OPS-c2021:16020-0] wal.WALSplitter: DistributedLogReplay = true
Seems easy enough to reproduce.
