Alex Liu commented on CASSANDRA-6084:
-------------------------------------

Agreed. The connection error is from

https://github.com/apache/cassandra/blob/cassandra-1.2/src/java/org/apache/cassandra/hadoop/AbstractColumnFamilyInputFormat.java#L272
, so it could be issue that the number of concurrent jobs fail to get the 
connections or some splits can't get the correct host. I will get some debug 
logs to see what's the exception.
                
> java.io.IOException: Could not get input splits

> I've noticed that if I restart Cassandra I get more errors for the first 
> minutes, although it's accessible through cqlsh without issue.
> I have tested on a 1-node (Osx Laptop) and 4-nodes (Ubuntu servers) and got 
> the same error. I tried with version 1.2.6, 1.2.8, 1.2.9, 1.2.10 without 
> success
