Cathy Daw commented on CASSANDRA-3192:
--------------------------------------

I noticed that after starting up the server, this error message was in the log 
file of the second node (non-seed) after startup.

*node2*

> On a 3 node brisk cluster (running against C* 1.0 branch), I was running the 
> java stress tool and the terasort concurrently in two sessions.  Eventually 
> both jobs failed with TimedOutException.
>   
> From this point forward most additional activity will fail with a 
> TimedOutException. 
> * Java Stress Tool - 5 rows / 10 columns - Operation [0] retried 10 times - 
> error inserting key 0 ((TimedOutException))
> * Hive - show tables: FAILED: Error in metadata: 
> com.datastax.bdp.hadoop.hive.metastore.CassandraHiveMetaStoreException: There 
> was a problem with the Cassandra Hive MetaStore: Could not connect to 
> Cassandra. Reason: Error connecting to node localhost
> However, the Cassandra CLI appears to be happy
> * Cassandra CLI: you can successfully insert and read using consistencylevel 
> as ONE or ALL
> The seed node has the following error repeatedly occurring in the logs.  The 
> other two nodes have no errors.
