["Cathy Daw (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/CASSANDRA-2572?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Cathy Daw updated CASSANDRA-2572:
---------------------------------

    Summary: cassandra_cli: CREATE CF HELP should list option as key_cache_save_period instead of keys_cached_save_period  (was: cassandra_cli: unable to create CF with keys_cached_save_period:  No enum const class org.apache.cassandra.cli.CliClient$ColumnFamilyArgument.KEYS_CACHED_SAVE_PERIOD )

Thanks David.  Will make this a bug about help.
