The problem is your hbase is not able to connect to Hadoop, can you put your hbase-site.xml content >> here.. have you specified localhost somewhere, if so remove localhost from everywhere and put your hdfsl namenode address suppose your namenode is running on master:9000 then put your hbase file system setting as master:9000/hbase here I am sending you the configuration which I am using in hbase and is working
