[jira] [Created] (HBASE-6487) assign region doesn't check if the
region is already assigned
Jimmy Xiang created HBASE-6487:
----------------------------------
Summary: assign region doesn't check if the region is already assigned
Key: HBASE-6487
URL: https://issues.apache.org/jira/browse/HBASE-6487
Project: HBase
Issue Type: Bug
Reporter: Jimmy Xiang
Tried to assign a region already assigned somewhere from hbase shell, the region is assigned to a different place but the previous assignment is not closed. So it causes double assignments. In such a case, it's better to issue a warning instead.

Can we also if something is in transition also here? Because internally in one of our code we are trying to use RIT also as a check?

------------------------------------
@Stack, are you ok for the patch? I think it is good even if OFFLINE state is not so trustful. It's better not to double assign.

------------------------------------
Sure. How about just checking the region state and make sure it is OFFLINE? If it is in other states, the region should be either opened or in transition, right?

getAssignedServer is not used by this patch? Its added by this patch but then not used.
This patch will work if OFFLINE state can be trusted (it should be more reliable after hbase-6060?)

[jira] [Updated] (HBASE-6487) assign region doesn't check if the
region is already assigned
Posted by "Jimmy Xiang (JIRA)" <ji...@apache.org>.

> Tried to assign a region already assigned somewhere from hbase shell, the region is assigned to a different place but the previous assignment is not closed. So it causes double assignments. In such a case, it's better to issue a warning instead.

------------------------------------
getAssignedServer is used for the first patch. It is not used for the second one. I thought it is useful so I kept it there. I can remove if we prefer to.
Yes, it will be more reliable after HBASE-6060.

-----------------------------------------------
So as per the patch we will only check if any region is in RIT (ie if it is in anyother state other than OFFLINE). If so skip the assignment. If not carry on.
Makes sense. Thanks for the patch Jimmy. +1

------------------------------------
Changed to Minor since it is a known issue:
Assign a region.Use with caution.If region already assigned,
this command will just go ahead and reassign
the region anyways. For experts only.
