In Hbase cluster, we can start hbase daemons with start-hbase.sh command or [crayon-59e580f2e6324931648803/] But in pseudo distribution mode (hbase.cluster.distributed=false), only HMaster daemon will be triggered but not the HRegionServer daemon or HQuorumPeer daemon. When we start the daemons with start-hbase.sh or individual hbase-daemon.sh commands for region server will not trigger daemon because […]
