Michaela Buergle updated HBASE-627:
-----------------------------------
Attachment: disableTable5.log
I've attached another case. Here table5 is being reassigned to the same server
(see disableTable5.log). In the log I find:
- RegionManager: Going to close region table5,,1210232134304
- ServerManager: Received MSG_REPORT_CLOSE : table5
- TableOperation: adding region table5,,1210232134304 to kill list
- ServerManager: Received MSG_REPORT_OPEN : table5
>From now on the RegionManager says: "Skipping region table5,,1210232134304
>because it is already closing." when selecting regions for reassignment.
And in HBaseAdmin.disableTable, we are "Waiting for first region to be disabled
from table5".
> Disable table doesn't work reliably

> Key: HBASE-627
> URL: https://issues.apache.org/jira/browse/HBASE-627
> Project: Hadoop HBase
> Issue Type: Bug
> Affects Versions: 0.2.0
> Environment: Hadoop/HBase on two nodes
> Reporter: Michaela Buergle
> Priority: Critical
> Fix For: 0.2.0
>
> Attachments: disableTable31.log, disableTable5.log

> 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:
> ...
> 2008-05-14 16:19:47,903 INFO org.apache.hadoop.hbase.client.HBaseAdmin:
> 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. ???
