    .I followed this guide(https://cwiki.apache.org/confluence/display/Hive/Hive+on+Spark%3A+Getting+Started). and i compiled hive from spark branch. in the next step i met the below error.. (*i typed the hive query on beeline, i used the simple query using "order by" to invoke the palleral works ex) select * from test where id = 1 order by id; ) [Error list is] 2014-09-04 02:58:08,796 ERROR spark.SparkClient (SparkClient.java:execute(158)) - Error generating Spark Plan java.lang.NullPointerException at org.apache.spark.SparkContext.defaultParallelism(SparkContext.scala:1262) at org.apache.spark.SparkContext.defaultMinPartitions(SparkContext.scala:1269) at org.apache.spark.SparkContext.hadoopRDD$default$5(SparkContext.scala:537) at org.apache.spark.api.java.JavaSparkContext.hadoopRDD(JavaSparkContext.scala:318) at org.apache.hadoop.hive.ql.exec.spark.SparkPlanGenerator.generateRDD(SparkPlanGenerator.java:160) at org.apache.hadoop.hive.ql.exec.spark.SparkPlanGenerator.generate(SparkPlanGenerator.java:88) at org.apache.hadoop.hive.ql.exec.spark.SparkClient.execute(SparkClient.java:156) at org.apache.hadoop.hive.ql.exec.spark.session.SparkSessionImpl.submit(SparkSessionImpl.java:52) at org.apache.hadoop.hive.ql.exec.spark.SparkTask.execute(SparkTask.java:77) at org.apache.hadoop.hive.ql.exec.Task.executeTask(Task.java:161) at org.apache.hadoop.hive.ql.exec.TaskRunner.runSequential(TaskRunner.java:85) at org.apache.hadoop.hive.ql.exec.TaskRunner.run(TaskRunner.java:72) 2014-09-04 02:58:11,108 ERROR ql.Driver (SessionState.java:printError(696)) - FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.spark.SparkTask 2014-09-04 02:58:11,182 INFO log.PerfLogger (PerfLogger.java:PerfLogEnd(135)) - </PERFLOG method=Driver.execute start=1409824527954 end=1409824691182 duration=163228 from=org.apache.hadoop.hive.ql.Driver> 2014-09-04 02:58:11,223 INFO log.PerfLogger (PerfLogger.java:PerfLogBegin(108)) - <PERFLOG method=releaseLocks from=org.apache.hadoop.hive.ql.Driver> 2014-09-04 02:58:11,224 INFO log.PerfLogger (PerfLogger.java:PerfLogEnd(135)) - </PERFLOG method=releaseLocks start=1409824691223 end=1409824691224 duration=1 from=org.apache.hadoop.hive.ql.Driver> 2014-09-04 02:58:11,306 ERROR operation.Operation (SQLOperation.java:run(199)) - Error running hive query: org.apache.hive.service.cli.HiveSQLException: Error while processing statement: FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.spark.SparkTask at org.apache.hive.service.cli.operation.Operation.toSQLException(Operation.java:284) at org.apache.hive.service.cli.operation.SQLOperation.runQuery(SQLOperation.java:146) at org.apache.hive.service.cli.operation.SQLOperation.access$100(SQLOperation.java:69) at org.apache.hive.service.cli.operation.SQLOperation$1$1.run(SQLOperation.java:196) at java.security.AccessController.doPrivileged(Native Method) at javax.security.auth.Subject.doAs(Subject.java:415) at org.apache.hadoop.security.UserGroupInformation.doAs(UserGroupInformation.java:1556) at org.apache.hadoop.hive.shims.HadoopShimsSecure.doAs(HadoopShimsSecure.java:508) at org.apache.hive.service.cli.operation.SQLOperation$1.run(SQLOperation.java:208) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:722) 2014-09-04 02:58:11,634 INFO exec.ListSinkOperator (Operator.java:close(580)) - 47 finished. closing... 2014-09-04 02:58:11,683 INFO exec.ListSinkOperator (Operator.java:close(598)) - 47 Close done 2014-09-04 02:58:12,190 INFO log.PerfLogger (PerfLogger.java:PerfLogBegin(108)) - <PERFLOG method=releaseLocks from=org.apache.hadoop.hive.ql.Driver> 2014-09-04 02:58:12,234 INFO log.PerfLogger (PerfLogger.java:PerfLogEnd(135)) - </PERFLOG method=releaseLocks start=1409824692190 end=1409824692191 duration=1 from=org.apache.hadoop.hive.ql.Driver>
