安裝hbase分佈式集羣出現的報錯- ERROR:org.apache.hadoop.hbase.PleaseHoldException: Master is initializing

可能的緣由以下：

1. 時間沒有同步

    HBase須要結點間的時間必須是同步的，能夠使用date命令在Linux查看時間（同步時間命令：ntpdate 1.cn.pool.ntp.org）

 

2. 底層採用的不是hdfs協議

    這個能夠經過查看hbase-site.xml中參數hbase.rootdir的值來羣定，一些其它的協議好比file協議等等，

     HBase也 是支持的

 

3.  ZooKeeper

     1) 查看zookeeper的狀態是否正常，能夠使用 zkServer.sh status 查看狀態，或者直接查看它的日誌

     2) 若是zookeeper的狀態正常，頗有可能就是防火牆阻擋了zookeeper的默認端口2181

 

實際解決方法：
