exactly like this . it 's some problem with zookeeper, i am not sure what
happen to zookeeper,
it is all started .but port 60030 and 60010 not ok.
---------------------------------------------------------------------------
futur...@test1:~/hbase$ bin/start-hbase.sh
test1: zookeeper running as process 18596. Stop it first.
master running as process 20047. Stop it first.
s1.idfs.cn: regionserver running as process 18829. Stop it first.
s2.idfs.cn: regionserver running as process 18763. Stop it first.
------------------------------------------------------------------------------------------
and logs in hbase give me the following, and i dont know how to deal with
it.if zookeeper is dead or goes with some problems,
