shankarlingayya created HBASE-9635:
--------------------------------------
Summary: 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
{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)
