---------------------------------------------

             Summary: Cannot drop keyspace Keyspace1 after running cassandra-stress
                 Key: CASSANDRA-5957
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-5957
             Project: Cassandra
          Issue Type: Bug
          Components: Core
         Environment: Cassandra 1.2.9 freshly built from cassandra-1.2 branch (f5b224cf9aa0f319d51078ef4b78d55e36613963)
            Reporter: Piotr Kołaczkowski


Steps to reproduce:
# Set MAX_HEAP="2G", HEAP_NEWSIZE="400M"
# Run ./cassandra-stress -n 50000 -c 400 -S 256
# The test should complete despite several warnings about low heap memory.
# Try to drop keyspace:
{noformat}
cqlsh> drop keyspace Keyspace1;
