Hi.

&n= bsp;

After updating Cassandra from 1= .1.5 to 1.1.6. Every schema updates ends with strange error exception in sy= stem.log and I must to restart nodes in cluster for whom `describe cluster`= says that nodes are unreachable.

Neither `nodetool repair` or `n= odetool upgragesstables` doesn’t help. Only double restarting of serv= ice helps, the first restart throws the same error, the second restart does= n’t and starts node normally.

 

Error log:
