Configuring HBase Thrift HA in MapR Clusters

AIM

Make HBase thrift HA with multiple thrift servers as ACTIVE.

Default behavior

If we have hbase thrift installed in to nodes, one will be shown as active and the other as standby.

Steps

Make changes in following file in all the hbase thrift server nodes

/opt/mapr/conf/conf.d/warden.hbasethrift.conf

#

# sed -i s/\1.1.1/`cat /opt/mapr/hbase/hbaseversion`/g /opt/mapr/conf/conf.d/warden.hbasethrift.conf

#

services=hbasethrift:all

service.displayname=HBaseThriftServer

service.command.start=/opt/mapr/hbase/hbase-1.1.1/bin/hbase-daemon.sh start thrift

service.command.stop=/opt/mapr/hbase/hbase-1.1.1/bin/hbase-daemon.sh stop thrift

service.command.type=BACKGROUND

service.command.monitorcommand=/opt/mapr/hbase/hbase-1.1.1/bin/hbase-daemon.sh status thrift

service.port=9090

service.ui.port=9095

service.logs.location=/opt/mapr/hbase/hbase-1.1.1/logs

service.process.type=JAVA

service.alarm.tersename=hbasethrift

service.alarm.label=HbaseThriftServiceDown

Once the changes are made, restart warden in all nodes

service mapr-warden restart

Once the warden comes up, you will see all the thrift servers in active state.

I have installed hbase thrift in 2 nodes. Below MCS screenshot shows that hbase thrift is up and running in two nodes.
