unbalance number fo region in cluster

i insert 2GB data into my hbase cluster ,but i find the region is not
balance,is insert operation always cause the region number different on
region server?

here is my 60010 output

Re: unbalance number fo region in cluster

Posted by Jean-Marc Spaggiari <je...@spaggiari.org>.
Can you please also checked on the HBase Web UI?
Do you have regions in transition?

Maybe the balancer already gave te balance plan, and regions are
moving, slowly, to their destinations? How big are those regions? I
mean, size in MB/GB and number of rows?

Re: unbalance number fo region in cluster

2013-07-05 10:11:24,894 INFO org.apache.hadoop.hbase.master.LoadBalancer:
Skipping load balancing.  servers=2 regions=145 average=72.5 mostloaded=73

Balancer saw 2 servers which were balanced - in terms of number of regions.

Where did CH36 go ?

Cheers

Re: unbalance number fo region in cluster

Posted by Ted Yu <yu...@gmail.com>.
Can you check load balancer related log lines in master log and put them on pastebin so that root cause can be diagnosed ?

Which HBase version are you using ?

Thanks

Re: unbalance number fo region in cluster

Posted by Azuryy Yu <az...@gmail.com>.
I supposed load balancer is enabled and there is no pre-split.

LB run periodicly, (5 mininutes by default), so after insert bulk data into
HBase, the table is unbalance but there will be balanced eventually after
round-robin load balancer running.

Re: unbalance number fo region in cluster

Posted by Ted Yu <yu...@gmail.com>.
bq. CH3u4

Did you mean CDH3u4 ?

How many tables do you have in total ?

Are regions from all the tables balanced across your cluster ?

Cheers

Re: unbalance number fo region in cluster

Posted by Ted Yu <yu...@gmail.com>.
Did you presplit your table ?

Was load balancer enabled ?

What HBase version do you use ?

Thanks
