---------------------------------------
Summary: system_drop_column_family hangs on trunk
Key: CASSANDRA-9910
URL: https://issues.apache.org/jira/browse/CASSANDRA-9910
Project: Cassandra
Issue Type: Bug
Components: Core
Reporter: Mike Adamson
Fix For: 3.0.0 rc1
{{system_drop_column_family}} is hanging on trunk. The code used to replicate
this is:
{noformat}
CfDef cfDef = new CfDef(ks, "new_cf_2");
client.system_add_column_family(cfDef);
client.system_drop_column_family(cfDef.name);
{noformat}
The call is hanging in {{ColumnFamilyStore.switchMemtable}} because the
memtable flush is failing with
{noformat}
