-------------------------------------

             Summary: Spark Plugin Exception - java.lang.ClassCastException: org.apache.spark.sql.catalyst.expressions.GenericMutableRow cannot be cast to org.apache.spark.sql.Row
                 Key: PHOENIX-2287
                 URL: https://issues.apache.org/jira/browse/PHOENIX-2287
             Project: Phoenix
          Issue Type: Bug
    Affects Versions: 4.5.2
         Environment: - HBase 1.1.1 running in standalone mode on OS X
- Spark 1.5.0
- Phoenix 4.5.2
            Reporter: Babar Tareen


Running the DataFrame example on Spark Plugin page (https://phoenix.apache.org/phoenix_spark.html) results in following exception. The same code works as expected with Spark 1.4.1.

{code:java}
    import org.apache.spark.SparkContext
    import org.apache.spark.sql.SQLContext
    import org.apache.phoenix.spark._

    val sc = new SparkContext("local", "phoenix-test")
    val sqlContext = new SQLContext(sc)

    val df = sqlContext.load(
      "org.apache.phoenix.spark",
      Map("table" -> "TABLE1", "zkUrl" -> "127.0.0.1:2181")
    )

    df
      .filter(df("COL1") === "test_row_1" && df("ID") === 1L)
      .select(df("ID"))
      .show
{code}
