2. copy /usr/local/hbase to centos2 and centos3

scp -r /usr/local/hbase root@centos2:/usr/local/

scp -r /usr/local/hbase root@centos3:/usr/local/

 

 

3.Start Hbase on centos1

start-hbase.sh

 

 

4. run JPS on each server

centos1

20071 HQuorumPeer

20137 HMaster

centos2

15930 HRegionServer

15838 HQuorumPeer

16010 HMaster

centos3

13639 HQuorumPeer

13737 HRegionServer

 

 

5. Test webpage

http://centos1:16010/  master

http://centos2:16010/  secondary master

http://centos2:16030/  RegionServers

http://centos3:16030/  RegionServers

 

 

6. Tell HBase whether it should manage it's own instance of Zookeeper or not. 

vi /usr/local/hbase/conf/hbase-env.sh

    export HBASE_MANAGES_ZK=false

scp /usr/local/hbase/conf/hbase-env.sh root@centos2:/usr/local/hbase/conf/hbase-env.sh

scp /usr/local/hbase/conf/hbase-env.sh root@centos3:/usr/local/hbase/conf/hbase-env.sh
