There is no real message written to the agent log other then:

    INFO  [ResourceContainer.invoker.nonDaemon-40] (org.rhq.plugins.cassandra.KeyspaceComponent)- Executing compaction on  keyspace [rhq]

Version-Release number of selected component (if applicable):
3.2.0.GA

How reproducible:
Always

Steps to Reproduce:
1. Install and start JBoss ON 3.2 system
2. After storage node is in inventory and reported as available, invoke the _Force Major Column Family Compaction_ operation on RHQ Storage Nodes / RHQ Storage Node(...) / Keyspaces / rhq / ColomnFamilies / raw_metrics

Actual results:
Compaction does not execute and operation status reports FAILURE with the exception and stack mentioned above.

Expected results:
Compaction operation runs as normal and operation status reports SUCCESS. Compaction is actually performed and rhq-storage.log reports something similar to:

    INFO [CompactionExecutor:76] 2014-07-09 18:33:17,065 CompactionTask.java (line 262) Compacted 2 sstables to [../../../rhq-data/data/rhq/raw_metrics/rhq-raw_metrics-ic-8,].  61,562,262 bytes to 51,079,953 (~82% of original) in 9,727ms = 5.008085MB/s.  5,943 total rows, 2,984 unique.  Row merge counts were {1:25, 2:2959, }

This is happening, because ColumnFamilyDiscoveryComponent is not setting SimpleValue for "name"-property which the operation on the other hand is trying to use.

The correct parameter name is available in resourceKey also. For some reason only "takeSnapshot" is using that as columnFamilyname, while repair and compact are not.

Fixed in master:
