Subject [jira] [Created] (CARBONDATA-1775) (Carbon1.3.0 - Streaming) Select query fails with java.io.EOFException when socket streaming is in progress
Date Mon, 20 Nov 2017 07:20:00 GMT
Chetan Bhat created CARBONDATA-1775:
---------------------------------------

             Summary: (Carbon1.3.0 - Streaming) Select query fails with  java.io.EOFException
when socket streaming is in progress
                 Key: CARBONDATA-1775
                 URL: https://issues.apache.org/jira/browse/CARBONDATA-1775
             Project: CarbonData
          Issue Type: Bug
          Components: data-query
    Affects Versions: 1.3.0
         Environment: 3 node ant cluster
            Reporter: Chetan Bhat


Steps :
User starts the thrift server using the command - bin/spark-submit --master yarn-client --executor-memory
10G --executor-cores 5 --driver-memory 5G --num-executors 3 --class org.apache.carbondata.spark.thriftserver.CarbonThriftServer
/srv/spark2.2Bigdata/install/spark/sparkJdbc/carbonlib/carbondata_2.11-1.3.0-SNAPSHOT-shade-hadoop2.7.2.jar
"hdfs://hacluster/user/hive/warehouse/carbon.store"
User connects to 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 creates a table and does streaming load in the table as per the script.

      }
    }
    thread.start()
    thread

val streamTableName = "stream_table"

sql(s"CREATE TABLE $streamTableName (id INT,name STRING,city STRING,salary FLOAT) STORED BY
'carbondata' TBLPROPERTIES('streaming'='true', 'sort_columns'='name')")

sql(s"LOAD DATA LOCAL INPATH 'hdfs://hacluster/tmp/streamSample.csv' INTO TABLE $streamTableName

sql(s"select * from $streamTableName").show

val carbonTable = CarbonEnv.getInstance(carbonSession).carbonMetastore.
  lookupRelation(Some("default"), streamTableName)(carbonSession).asInstanceOf[CarbonRelation].carbonTable

val tablePath = CarbonStorePath.getCarbonTablePath(carbonTable.getAbsoluteTableIdentifier)

val port = 7995
val serverSocket = new ServerSocket(port)
val socketThread = writeSocket(serverSocket)
val streamingThread = startStreaming(carbonSession, tablePath, streamTableName, port)

While load is in progress user executes select query on the streaming table from beeline.
0: jdbc:hive2://10.18.98.34:23040> select * from stream_table;

Issue : The Select query fails with  java.io.EOFException when socket streaming is in progress.

Also when user checks the spark shell terminal there are exceptions thrown.
