I'm having an issue that prevents me from starting Cassandra daemon.
I'm using Cassandra Community 2.1.4
I created my cluster several hours ago, and it was working perfectly until I rebooted the azure VM which is hosting this node. My cluster uses password authentication.
Any idea ?
edit : I dont know if it is relevant, but I tried to drop a keyspace before rebooting, and it failed. (no, i have not tried to drop system_auth keyspace, in case you wonder)
Cassandra log file contains:

Several lines ago in log file:
WARN [main] 2015-04-14 14:06:59,068 CommitLogReplayer.java:139 - Encountered bad header at position 16 of commit log /var/lib/cassandra/commitlog/CommitLog-4-1429010621980.log, with invalid CRC. The end of segment marker should be zero.
Any way to fix that ?
