The spark to read data in hbase-CodePudding

Recently started learning, the spark in the spark to read data in hbase this stage, an exception, baidu for a long time and can't get everything right, I use the IDE eclipse, scala's version is 2.11.6 hbase version 1.2.6, spark is version 2.1.0, hadoop version is 2.7.3 (test), I didn't use my own zookeeper, using 3.4.6 version, single use hbase - shell used to delete data is no problem, the corresponding jar package I also in the hbase jar added to the project of the spark, I machines are pseudo distributed, only a computer, hadoop and spark are pseudo-distributed, code is as follows:
The object Test {
Def main (args: Array [String]) {
Val conf=HBaseConfiguration. The create ();
The conf. Set (" hbase. Zookeeper. Quorum ", "192.168.0.102")
The conf. Set (" hbase. Zookeeper. Property. ClientPort ", "2181")
Val sc=new SparkContext (new SparkConf () setMaster (" local "). SetAppName (" Hbase - test "))
The conf. Set (TableInputFormat INPUT_TABLE, "student")
Val stuRDD=sc. NewAPIHadoopRDD (conf, classOf [TableInputFormat], classOf [. Org. Apache hadoop, hbase. IO. ImmutableBytes
Writable], classOf [. Org. Apache hadoop, hbase client. The Result])
Val count=stuRDD. The count ()
Println (" Students RDD Count: "+ Count)
StuRDD. Cache ()
StuRDD. Foreach ({case (_, result)=& gt; Val key=Bytes. ToString (result. GetRow)
Val name=Bytes. ToString (result. GetValue (" info ". GetBytes, "name" getBytes))
Val gender=Bytes. ToString (result. GetValue (" info ". GetBytes, "gender". GetBytes))
Val age=Bytes. ToString (result. GetValue (" info ". GetBytes, "age" getBytes))
Println (" Row Key ":" + Key + "Name:" + Name + "Gender:" + "Age:" + + Gender Age)
})

}
}

Exceptions are as follows:

Omit part of unrelated, at first I think is my zookeeper configuration has a problem, I try to use hbase own zookeeper, error is still the same,
