Environment: Ubuntu 14.04, hadoop-2.2.0, hbase-0.98.7
when I run hasoop and hbase (one node mode), both succeed (I also check the site 8088 for hadoop, 60010 for hbase)
jps
4507 SecondaryNameNode
5350 HRegionServer
4197 NameNode
4795 NodeManager
3948 QuorumPeerMain
5209 HMaster
4678 ResourceManager
5831 Jps
4310 DataNode
but when I check hbase-hadoop-master-localhost.log, I found the information following
2014-10-23 14:16:11,392 INFO [main-SendThread(localhost:2181)] zookeeper.ClientCnxn: Opening socket connection to server localhost/127.0.0.1:2181. Will not attempt to authenticate using SASL (unknown error)

I have a google website for this unknown error problem, but I cannot solve this problem ... Below is the configuration of myoop and hbase.
