Oracle Table not resolved [Spark 2.1.1]

2017-08-28 Thread Imran Rajjad 
Hello,

I am trying to retrieve an oracle table into Dataset using following
code

String url = "jdbc:oracle@localhost:1521:ora";
  Dataset jdbcDF = spark.read()
  .format("jdbc")
  .option("driver", "oracle.jdbc.driver.OracleDriver")
  .option("url", url)
  .option("dbtable", "INCIDENTS")
  .option("user", "user1")
  .option("password", "pass1")
  .load();

  System.out.println(jdbcDF.count());

below is the stack trace
