Jim Kellerman updated HBASE-627:
--------------------------------
Attachment: patch.txt
HConnection
- tableExists now throws MasterNotRunningException if instance is not on-line
- added method isTableEnabled
HConnectionManager
- tableExists, getRegionLocation, listTables, locateRegion, relocateRegion,
getHRegionConnection, getRegionServerWithRetries now check to see if master is
running
- added method isTableEnabled
- getHTableDescriptor now checks if table exists, uses ScannerCallable instead
of HTable.getScanner
HBaseAdmin
- enableTable, disableTable are now synchronous and wait until entire table is
enabled/disabled and use HConnection.isTableEnabled to make the check
- added methods isTableEnabled(Text), isTableEnabled(String),
isTableEnabled(byte[]). They use HConnection.isTableEnabled
HTable
- renamed isTableOnline methods to isTableEnabled, now use
HConnection.isTableEnabled
- removed isTableOffline methods since they are redundant
> 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
> Assignee: Jim Kellerman
> Priority: Critical
> Fix For: 0.2.0
>
> Attachments: disableTable31.log, disableTable5.log, patch.txt
>
>
> 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. ???
