Eu tenho two linux a máquina um é master machine(192.168.8.174) e outra é slave1 machine(192.168.8.173) . Eu instalei e configurei Hadoop 2.6.0 no modo totalmente distribuído com sucesso. A saída do Hadoop também vem perfeitamente. Eu instalei e configurei HBase 1.0 .i usei hbase default zookeeper .i didn't installed separate zookeeper .Quando eu inicio o hbase ele mostra erro em hbase log file como abaixo

slave1 /etc/hosts

192.168.8.174     master
192.168.8.173     slave1

e eu testei ambos Boolean para HBASE_MANAGES_ZK é verdadeiro ou falso em hbase-env.sh mas ainda não consegui encontrar

eu não sei o que eu estou enganado dar alguma solução ..

Eu tenho KeeperErrorCode = ConnectionLoss para a exceção / hbase, mas seguindo o trabalho de configuração para mim: Alterar no hbase-env.sh: 

export HBASE_MANAGES_ZK=true

Mude o seguinte em ams-hbase-site: 

                <configuration>
                <property> 
                <name>hbase.zookeeper.quorum</name>
