+1 on jimmy v2 for me.
(it will be nice also having the MetaEditor.overwriteRegions test and the add 
regions debug committed, but I guess i can create another jira for them)

Jimmy Xiang commented on HBASE-10349:
-

The test is ok locally.  Let me take a look and post a new patch.

[~mbertozzi], it is a racing between table deletion and balancer.  The balancer 
operates on a "copy" of the region assignments. When the balancer tries to 
balance a region, the region has been deleted (including the meta entry), and 
the table is removed (including the znode).  In assigning the deleted region, 
the region server puts the region back in the meta again with just the server 
info. That's why the region info in the meta row is missing.

[jira] [Commented] (HBASE-10349) Table became unusable when master balanced its region after table was dropped

Matteo Bertozzi commented on HBASE-10349:
-

[~jxiang] can you explain why the region is still in META?
the patch looks good to me to avoid any assignment transition after delete,
but I still don't see anything in the balancer/assignment manager that can add 
back the region to META.

Matteo Bertozzi commented on HBASE-10349:
-

I think that 10348-v1 a good check to have, for the assignment
but is probably just half of the fix.

the other part is on table creation, the region is still visible in META.
and I don't think that the assignment adds the region back to META.

[jira] [Commented] (HBASE-10349) Table became unusable when master balanced its region after table was dropped

Matteo Bertozzi commented on HBASE-10349:
-

maybe related to this.. 
META should have DELETE -> PUT (restore snapshot) -> DELETE... but the row 
looks not deleted from MetaReader.tableExists()
{code}
  public static void overwriteRegions(CatalogTracker catalogTracker,
  List regionInfos) throws IOException {
deleteRegions(catalogTracker, regionInfos);
// Why sleep? This is the easiest way to ensure that the previous deletes 
does not
// eclipse the following puts, that might happen in the same ts from the 
server.
// See HBASE-9906, and HBASE-9879. Once either HBASE-9879, HBASE-8770 is 
fixed,
// or HBASE-9905 is fixed and meta uses seqIds, we do not need the sleep.
Threads.sleep(20);
addRegionsToMeta(catalogTracker, regionInfos);
LOG.info("Overwritten " + regionInfos);
  }

Matteo Bertozzi commented on HBASE-10349:
-

was MetaReader.tableExists()... and the rows seems directly from the meta 
table...
any chances that we failed the MetaEditor.deleteRegions() or we are reading old 
data from META?
the request to delete the region was sent

Matteo Bertozzi commented on HBASE-10349:
-

I guess the problem has more to do with the disable step.

from the logs looks like the region afc82d1ceabbaca36a504b83b65fc0c9 was in the 
list of region to delete, 
since there is the log of "Archiving region". so it should also be removed from 
meta by the MetaEditor.deleteRegions()
{code}
15909  2014-01-15 09:41:43,651 DEBUG [MASTER_TABLE_OPERATIONS-hor15n05:6-0] 
handler.DeleteTableHandler: Archiving region 
tablethree_mod,,1389778226606.afc82d1ceabbaca36a504b83b65fc0c9. from FS
{code}

looking at the MetaEditor.tableExists() to see if is reading from META or from 
the znode..
