Description

Running stress write (thrift) on 2.1 branch is resulting in the following.

Note: this is after working around JAVA-276 causing stress to fail to connect to 2.1.

$ ./tools/bin/cassandra-stress write n=5000000

Seems to be just a thrift issue, as running stress write using the native protocol works:

$ ./tools/bin/cassandra-stress write n=5000000 -mode native cql3

Attaching stress write and system logs as well.
