Michaela Buergle commented on HBASE-627:
----------------------------------------

Yes, I am sure I've updated. I can still observe the behaviour described above.

I did read in HBASE-615 that there might be some oscillation due to balancing 
but the fact that this oscillation affects enabling/disabling of tables has not 
been mentioned to my knowledge.
In my case, I wouldn't speak of oscillation though. Often it is just one region 
being assigned to the other one of my two nodes, which is certainly not unusual 
after having created a table. After all this is what the balancing is about. 
Still this reassignment and the more or less simultaneous disabling don't seem 
to go together well.

>         Environment: Hadoop/HBase on two nodes

> When creating a couple of tables like this:
> 1) create an empty table
> 2) disable table, add new column family, enable table
> 3) put 100 small documents into newly created column
> around once in 10 tries the disable doesn't happen.
> I have no clue as to why the table isn't disabled in the first place, but if 
> this occurs, two things in HBaseAdmin.disableTable() strike me as odd:
> - after numRetries tries to wait for disabling we exit the loop; there is no 
> exception or error message:
> ...

> Disabled table table31
> 2008-05-14 16:19:47,910 INFO org.apache.hadoop.ipc.Server: IPC Server handler 
> 3 on 60000, call addColumn(table31, {name: document, max versions: 3, 
> compression: NONE, in memory: false, block cache enabled: false, max length: 
> 2147483647, time to live: FOREVER, bloom filter: none}) from 
> XXX.XX.40.36:47116: error: org.apache.hadoop.hbase.TableNotDisabledException: 
> table31
> ...
> - the scanner iterates over HRegionInfos of several tables. If any one of 
> those is disabled, we also leave the loop as if the requested table had been 
> disabled.
> I've had this disabling problem occur quite reliably over the last days - 
> today I couldn't reproduce it, though HBase version hasn't changed. ???
