      Description

      Steps :
      Spark submit thrift server is started.
      User starts spark shell using the command - bin/spark-shell --master yarn-client --executor-memory 10G --executor-cores 5 --driver-memory 5G --num-executors 3 --jars /srv/spark2.2Bigdata/install/spark/sparkJdbc/carbonlib/carbondata_2.11-1.3.0-SNAPSHOT-shade-hadoop2.7.2.jar

      In spark shell User tries to start streaming with table streaming property altered from default(false) to true.
