Have you tried the -metaOnly hbck option (possibly in conjunction with
-fixAssignments/-fix)? It could be that meta is out of whack which
prevents everything else from making progress.
If that doesn't work please share more logs -- it will help us figure out
where it got stuck.
Thanks,
Hi,
I can nolonger start my cluster correctly and get messages like

I suppose Hbase is not done for being stopped but only for having some nodes
going down ??? HDFS is not complaining, it's only HBase that can't start
correctly :(

Hi,
I didn't hear about the possibility to split by regex. May somebody else will
post here if it's possible.
But you could maybe workaround that by doing a mapping from regex to region in
your client code.
If that's not an option and it's too difficult to decide how to pre-split you
could

Yesterday I stopped my cluster because of a storm. It did not went up
well so I have formated the hadoop FS and restarted it.

It's telling me that the table don't exist when I want to delete it,
but that the table exist

Hi JM,
So you already wiped everything on the HDFS level? The only thing left is
ZooKeeper. It should not hold you back, but it could be having an entry in
/hbase/table? Could you try the ZK shell and do an ls on that znode?
If at all, if you wipe HDFS anyways, please also try wiping the ZK
Hi Lars,
For for pointing me to the right direction.
I have already restarted ZK but I did not removed anything on its server.

Hi JM,
You can simply remove the znode's if you like, that ought to do it.

Seems that everything is now working fine after I removed the entries.

a bit before doing that.

No, you need to know your key ranges for each split. If you don't and you guess
wrong, you may end up not seeing any benefits because your data may still end
up going to a single region...
(Its data dependent.)
I am personally not a fan of pre-splitting a table.
The way I look at it, you

My organization has been doing something zany to simulate atomic row operations

We have a converter-object model for the writables that are populated in an

Other than the lack of hbck is there any thing else it prevents from
working?
If not it may be our best option to pull the data and make a new table

Interesting... Can you read the file? Try a hadoop dfs -cat on it
and see if it goes to the end of it.
It could also be useful to see a bigger portion of the master log, for
all I know maybe it handles it somehow and there's a problem
elsewhere.
Finally, which Hadoop version are you using?

Pablo, instead of CMSIncrementalMode try UseParNewGC.. That seemed to be the

Hi all,
I've implemented an indexing system. It needs refinement of course
but I have my own work to do, so I decided to open it for everyone to
access, modify and any improvement or ideas would be great.

HBase is quite HUGE
The timeout can be configured using the session timeout configuration. The
default for that is 180s, but that means that if the RS doesn't heartbeat to ZK
for 180s, it's considered dead. Unless the machines are really loaded or GCs
are pausing the RS processes, I don't see any other reason
Funny you mention that. I asked the techs to set it up that why.
I went to pull my ZK logs and found that 1 RS is still running. What is
interesting is that RS is connected to ZK on devrackA-05. The 2 RSes
that died where connected to ZK on devrackA-03. devrackA-03 has ZK and
HMaster on it.
Is your ZK managed by HBase or are you managing it yourself?
BTW - All ZK nodes should be reachable by all nodes in the cluster.
The YouAreDeadException would be in RS logs if at all.
