• 安装hbase分布式集群出现的报错- ERROR:org.apache.hadoop.hbase.PleaseHoldException: Master is initializing


    可能的原因如下:

    1. 时间没有同步

        HBase需要结点间的时间必须是同步的,可以使用date命令在Linux查看时间(同步时间命令:ntpdate 1.cn.pool.ntp.org)

    2. 底层采用的不是hdfs协议

        这个可以通过查看hbase-site.xml中参数hbase.rootdir的值来群定,一些其它的协议比如file协议等等,

         HBase也 是支持的

    3.  ZooKeeper

         1) 查看zookeeper的状态是否正常,可以使用 zkServer.sh status 查看状态,或者直接查看它的日志

         2) 如果zookeeper的状态正常,很有可能就是防火墙阻挡了zookeeper的默认端口2181

    实际解决方法:
