Subject Invalid compacted_at timestamp entries in Cassandra 2.0.5
Date Mon, 03 Mar 2014 14:43:13 GMT
Running 'nodetool compactionHistory' seems to be showing strange timestamp
values for the 'compacted_at' column. e.g.
id                                                      keyspace_name     
columnfamily_name            compacted_at              bytes_in      
bytes_out      rows_merged
cb035320-9f11-11e3-82e3-e37a59d03017     system             sstable_activity            
1212036306964769          74352          19197          {1:19, 4:427}

And running a CQL query on the system.compaction_history table shows dates
well in the future.

 id                                                        | bytes_in |
bytes_out | columnfamily_name       | compacted_at              |
keyspace_name      | rows_merged
--------------------------------------+----------+-----------+-------------------------+---------------------------+--------------------+--------------------------
 bda494f0-9db8-11e3-bb85-ed7074988754 |      647 |       320 |
compactions_in_progress | 17391-03-07 12:26:35+0000 |             system |            
{1: 3, 2: 1}
 dc87cd00-a269-11e3-a1a8-ed7074988754 |      410 |       159 |
compactions_in_progress | 33738-09-07 17:03:21+0100 |             system |            
{1: 2, 2: 1}

Is this a known issue or something wrong on our system?

Thanks
Phil
