Spark操作HBase报:org.apache.hadoop.hbase.client.RetriesExhaustedWithDetailsException异常解决方案

一.异常信息

二.代码

 val config = HBaseConfiguration.create()
 config.set("hbase.zookeeper.quorum", "hbase01,hbase02,hbase03")
 config.set("hbase.zookeeper.property.clientPort", "2181")
 val connection = ConnectionFactory.createConnection(config)
 val admin = connection.getAdmin
 val table = connection.getTable(TableName.valueOf("ZHEN:TABLENAME"))

三.解决方案

　　1.在代码标红的地方把库名+表名全部大写，中间用":"间隔。

　　2.Hbase版本不一致【服务器上启动的Hbase和Spark导入的Hbase-lib不一致】。

　　3.hdfs的datanode或namenode宕机。

　　4.Hbase的Hmaster或者HRegionServer挂了。
