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。
