What are you memory allocations set to? When using something as expensive as LIKE and a date range together, I often have to increase my standard memory allocation.
Try changing your memory allocation settings to: Key: mapreduce.map.memory.mb Value: 2048 and Key: mapreduce.map.java.opts Value: -Xmx1500m In HUE, this is the settings tab and you enter them manually. I’m unsure about command line.

In the schema definition, we have a parquet struct called device with a string field user_agent. If we run query from Example 1, it returns results as expected. If we run query from Example 2, execution fails and exits with error. Did anyone face a similar case? Thanks! Example 1: SELECT device.user_agent FROM sometable WHERE ds >= '2016-03-30 00' AND ds <= '2016-03-30 01' LIMIT 1; Example 2: SELECT device.user_agent FROM sometable WHERE ds >= '2016-03-30 00' AND ds <= '2016-03-30 01' AND device.user_agent LIKE 'Mozilla%' LIMIT 1; The error and trace we get is: Exception from container-launch. FAILED: Execution Error, return code 2 from org.apache.hadoop.hive.ql.exec.mr.MapRedTask Container exited with a non-zero exit code 1 Stack trace: ExitCodeException exitCode=1: at org.apache.hadoop.util.Shell.runCommand(Shell.java:545) at org.apache.hadoop.util.Shell.run(Shell.java:456) at org.apache.hadoop.util.Shell$ShellCommandExecutor.execute(Shell.java:722) at org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor.launchContainer(DefaultContainerExecutor.java:212) at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:302) at org.apache.hadoop.yarn.server.nodemanager.containermanager.launcher.ContainerLaunch.call(ContainerLaunch.java:82) at java.util.concurrent.FutureTask.run(FutureTask.java:262) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:745) ________________________________ This e-mail message is authorized for use by the intended recipient only and may contain information that is privileged and confidential.
