Also, I did try repairHoles, all fix options but in vain. I restarted
master atleast thrice.

Regions should never overlap
Incase a region is in transition for a long long time, you could possibly
force Unassign a region , if you are ok to lose the region.

i issued unassign and close_region both but the region is still in
transition also I deleted the .META entry for the region. Do I need to
restart master ?

Was the unassigning successful ?
If not you can force it by - unassign 'REGIONNAME', true

We ran the command unassign 'REGIONNAME',true the output is "completed in
57 sec", but still region is in transition.

Can you mention the state of the region.. You can find the details in you

Hi,
I tried to run hbase hbck -fixMeta after master restart. and in the output
I got
There is a hole in the region chain between You need to create
a new .regioninfo and region dir in hdfs to plug the hole for about 10 odd
regions
What does this mean ?
On Fri, Feb 8, 2013 at 12:20 PM, kiran
What is the version that you are using? You can run the tool called HBCK
which should help you.
But before running this what operation were you trying to make? DISABLED
and then ENABLED a table or it was just normal region assignments while
creating table or
region balancing?

On Fri,
Hi, Kiran
Welcome to beautiful world of HBase transition states :) . When i face
RIT issue this are steps that i use to resolve it:
1. hbase hbck -fixAssignments (this depends on your version of hbase
it can be also just -fix)
If you don't have luck with 1. then you will need manual intervention
Yes, RIT states were bit confusing for the end user. In the latest version
lot of efforts have gone into solve this problems. Hope for the best in the
future :)
Regards
Ram

Thanks samar and ramakrishna
I did use option 2 and deleted /hbase from the zkcli shell. I restarted the
cluster now there are more regions in transition. Will it take some time to
complete since it is a new assignment ?
My hase version is 0.94.1, and I have a doubt with the property
hbase.hregio
after some searching i found that main reason for regions with same keys is
splitting and it is the culprit in our case for inconsistency. But I set my
filesize to a very large size but i am unsure why still splitting is
happening

Okie. So if you don't mind can you attach your logs. What is the split
policy and what is the size of the region?
Its better we take a look at it and solve the problem if it is a kernel
problem.

I think it might be reason for the splits. From 0.94.0, seems the default
split policy has changes

Can you pick a few regions stuck in transition and check related region
server logs to see why they couldn't be assigned ?
Which release were you using previously ?
Thanks

Following up, if I look at the MBase Master UI in the Ambari console I see
links to
all of the region servers. If I click on those links, the Region Server page
comes
up and in the Regions section, is displays ‘Not serving regions’. I’m not sure
if that means something is disabled, or it just doe

You should really find out where you hmaster ui lives (there is a master UI
for every node provided by the apache project) because it gives you
information on the state of your system, but if you want to skip all that,
here are the instructions for OfflineRepair, without knowing what is

I’m familiar with the HMaster UI. I’m looking at it now. It does not contain
the information you describ
Update on this:
deleting the contents the /hbase-unsecure/region-in-transition node did fix my
problem with
HBase finding my table regions.
I'm still have a problem though, possibly related. I’m seeing OutOfMemory
errors in the region server logs (modified slightly):
2015-12-23 06:52:37,466 IN
I appear to have resolved the OOM error by greatly increasing the max process
limit (to 64K). Using HDP 2.1
a limit of 1024 seemed to be working OK. I’m surprised I had to make a change
of this magnitude.

(Just to avoid confusion, Lars is talking about HBase Table CF's blocksize,
unrelated to HDFS block sizes, which would be fine if set to 512m.)

You should check RS logs to see why regions can not be assigned.
