啟動Hbase：start-hbase.sh

我採用配置引數是hbase自帶的Zookeeper，之前反覆重啟幾次，會正常登陸，現在採用自己安裝的Zookeeper，啟動hbase，關閉Hbase的自帶的開關：
修改 vi hbase-env.sh
128 # export HBASE_MANAGES_ZK=true //128行註釋使用自己安裝的Zookeeper，將Zookeeper的zoo.cfg 拷貝到 hbase目錄下的conf目錄中
cp ~/training/zookeeper-3.4.10/conf/zoo.cfg ~/training/hbase-1.3.1/conf/
接著先啟動本地的Zookeeper，再啟動hbase，接著登陸hbase shell 登陸成功；
[[email protected] zookeeper-3.4.10]# zkServer.sh start
[[email protected] zookeeper-3.4.10]# start-hbase.sh
[[email protected] zookeeper-3.4.10]# hbase shell
hbase(main):001:0> list

放棄本地的hbase 改用自己安裝的hbase 可以暫時解決 hmaster 登陸閃退的情況
