Spark : java.io.NotSerializableException: org.apache.hadoop.hbase.client.Result

[Madabhattula Rajesh Kumar <mr...@gmail.com>]

Hi Team,

I'm getting below exception. Could you please me to resolve this issue.

Below is my piece of code

val rdd = sc.newAPIHadoopRDD(conf, classOf[TableInputFormat],
classOf[org.apache.hadoop.hbase.io.ImmutableBytesWritable],
classOf[org.apache.hadoop.hbase.client.Result])

var s =rdd.map(x => x._2)

var a = test(s.collect)

def test(s:Array[org.apache.hadoop.hbase.client.Result])
{

  var invRecords = HashMap[String, HashMap[String, String]]()
 s foreach (x => {
        var invValues = HashMap[String, String]()
        x rawCells () foreach (y => { invValues += Bytes.toString(y
getQualifier) -> Bytes.toString(y getValue) })
        invRecords += Bytes.toString(x getRow) -> invValues
      })
println("********************* === "+invRecords.size)

}
