Hi, I am trying to use spark to perform some basic text processing on news articles Recently I am facing issues on codes which ran perfectly well on the same data before
I am pasting the last few lines, including the exception message. I am using python. Can anybody suggest a remedy Thanks, Sunandan 14/10/21 01:52:23 ERROR TaskSchedulerImpl: Lost executor 10 on beaker-3.news.cs.nyu.edu: remote Akka client disassociated 14/10/21 01:52:23 INFO TaskSetManager: Re-queueing tasks for 10 from TaskSet 1.0 14/10/21 01:52:23 WARN TaskSetManager: Lost task 8.2 in stage 1.0 (TID 29, beaker-3.news.cs.nyu.edu): ExecutorLostFailure (executor lost) 14/10/21 01:52:23 WARN TaskSetManager: Lost task 11.2 in stage 1.0 (TID 31, beaker-3.news.cs.nyu.edu): ExecutorLostFailure (executor lost) 14/10/21 01:52:23 WARN TaskSetManager: Lost task 9.2 in stage 1.0 (TID 28, beaker-3.news.cs.nyu.edu): ExecutorLostFailure (executor lost) 14/10/21 01:52:23 WARN TaskSetManager: Lost task 10.2 in stage 1.0 (TID 30, beaker-3.news.cs.nyu.edu): ExecutorLostFailure (executor lost) 14/10/21 01:52:23 INFO DAGScheduler: Executor lost: 10 (epoch 12) 14/10/21 01:52:23 INFO BlockManagerMasterActor: Trying to remove executor 10 from BlockManagerMaster. 14/10/21 01:52:23 INFO BlockManagerMaster: Removed 10 successfully in removeExecutor 14/10/21 01:52:23 INFO AppClient$ClientActor: Executor updated: app-20141021015207-0000/10 is now EXITED (Command exited with code 53) 14/10/21 01:52:23 INFO SparkDeploySchedulerBackend: Executor app-20141021015207-0000/10 removed: Command exited with code 53 14/10/21 01:52:23 ERROR SparkDeploySchedulerBackend: Application has been killed.
