HBase 連結問題

總結寫之前spark連結hbase的坑。

• 異常

Will not attempt to authenticate using SASL (unknown error)
ClusterId read in ZooKeeper is null

• HBase 配置程式碼

val hBaseConf = HBaseConfiguration.create()
hBaseConf.set("hbase.zookeeper.quorum","fp-bd6,fp-bd5")
hBaseConf.set("hbase.zookeeper.property.clientPort"
 
,"2181")
hBaseConf.set("hbase.defaults.for.version.skip","true")

• 解決方法

  新增 hBaseConf.set("zookeeper.znode.parent","/hbase-unsecure")
The value of zookeeper.znode.parent in HBASE_CONF/hbase-site.xml is specified as /hbase-unsecure (see below) which is correct but for some reason (still trying to figure this out), the value being printed is /hbase. So currently I’ve overridden this programatically in the client program by adding the following line to the program。
  大致意思是：雖然hbase-site.xml配置了hbase-unsecure，這是正確的。但由於某種原因（仍然試圖弄清楚），列印的值是/ hbase。
  官方文件中有提到：If both clusters use the same ZooKeeper cluster, you must use a different zookeeper.znode.parent, because they cannot write in the same folder。
  所以這裡需要單獨設定zookeeper.znode.paren 的屬性。
