Question

我需要使用Zeppelin构建一个分析解决方案，从Oracle，Hadoop，Hbase读取数据，现在我需要通过zeepelin spark解释器将分析结果保存到hbase，我编写了一个演示代码，这个演示工作在Spark开发环境中，但它在齐柏林飞艇中无效。

有人可以帮助我，谢谢。

 %spark
import org.apache.spark.sql.{DataFrame, Row, SQLContext}
import org.apache.hadoop.hbase.util.Bytes
import org.apache.hadoop.hbase.client.Put
import org.apache.hadoop.hbase.io.ImmutableBytesWritable
import org.apache.hadoop.hbase.client.Result
import org.apache.hadoop.hbase.mapreduce.TableOutputFormat
import org.apache.hadoop.mapreduce.Job

var sql="select * from analyticresult"

val sqlContext = sqlc

import sqlContext.implicits._
val list = sqlContext.sql(sql)


def getJob(tableName: String): Job = {
    sc.hadoopConfiguration.set("hbase.zookeeper.quorum", "dn1.hadoop,dn2.hadoop,dn3.hadoop,dn4.hadoop,dn5.hadoop")
    sc.hadoopConfiguration.set("hbase.zookeeper.property.clientPort", "2181")
    sc.hadoopConfiguration.set(TableOutputFormat.OUTPUT_TABLE, tableName)

    val job = Job.getInstance(sc.hadoopConfiguration)
    job.setOutputKeyClass(classOf[ImmutableBytesWritable])
    job.setOutputValueClass(classOf[Result])
    job.setOutputFormatClass(classOf[TableOutputFormat[ImmutableBytesWritable]])
    job
  }

val hbaseRDD = list.mapPartitions( iter => {
      iter.map( it => {
        var rowkey = it.getAs[String](8).getBytes
        var put = new Put(rowkey) //set rowkey
        put.addColumn(Bytes.toBytes("A"), Bytes.toBytes("CI"), it.getAs[String](3).getBytes)
        put.addColumn(Bytes.toBytes("A"), Bytes.toBytes("CT"), it.getAs[String](4).getBytes) 
        //Bytes.toBytes(it.getLong(9))

        (new ImmutableBytesWritable, put)

      })
    })

var table = getJob("HWBTEST") 
hbaseRDD.saveAsNewAPIHadoopDataset(table.getConfiguration)

zeppelin控制台：编译代码正常，但有IllegalStateException。
