Andrew Kyle Purtell resolved HBASE-9635.
----------------------------------------
Resolution: Incomplete
> HBase Table regions are not getting re-assigned to the new region server when
> it comes up (when the existing region server not able to handle the load)

> Key: HBASE-9635
> URL: https://issues.apache.org/jira/browse/HBASE-9635
> Project: HBase
> Issue Type: Bug
> Components: master, regionserver
> Affects Versions: 0.94.11
> Environment: SuSE11
> Reporter: shankarlingayya
> Priority: Major
>
> {noformat}
> HBase Table regions are not getting assigned to the new region server for a
> period of 30 minutes (when the existing region server not able to handle the
> load)
> Procedure:
> 1. Setup Non HA Hadoop Cluster with two nodes (Node1-XX.XX.XX.XX,
> Node2-YY.YY.YY.YY)
> 2. Install Zookeeper & HRegionServer in Node-1
> 3. Install HMaster & HRegionServer in Node-2
> 4. From Node2 create HBase Table ( table name 't1' with one column family
> 'cf1' )
> 5. Perform addrecord 99649 rows
> 6. kill both the node Region Server and limit the Node1 Region Server FD to
> 600
> 7. Start only the Node1 Region server ==> so that FD exhaust can happen in
> Node1 Region Server
> 8. After some 5-10 minuites start the Node2 Region Server
> ===> Huge number of regions of table 't1' are in OPENING state, which are not
> getting re assigned to the Node2 region server which is free.
> ===> When the new region server comes up then the master should detect and
> allocate the open failed regions to the region server (here it is staying the
> OPENINING state for 30 minutes which will have huge impcat user app which
> makes use of this table)
