Karthik Kambatla commented on HADOOP-11878: ------------------------------------------- By the way, I checked none of the direct callers check for NPE and their javadocs don't necessarily mention throwing an NPE if the path is null either. There is a possibility of some indirect caller catching NPE in case the path is null, but I would think that is pretty bleak. > FileContext.java # fixRelativePart should check for not null for a more > informative exception > --------------------------------------------------------------------------------------------- > > Key: HADOOP-11878 > URL: https://issues.apache.org/jira/browse/HADOOP-11878 > Project: Hadoop Common > Issue Type: Bug > Reporter: Brahma Reddy Battula > Assignee: Brahma Reddy Battula > Labels: BB2015-05-TBR > Attachments: HADOOP-11878-002.patch, HADOOP-11878-003.patch, > HADOOP-11878-004.patch, HADOOP-11878.patch > > > Following will come when job failed and deletion service trying to delete the > log fiels > 2015-04-27 14:56:17,113 INFO > org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor: Deleting > absolute path : null > 2015-04-27 14:56:17,113 ERROR > org.apache.hadoop.yarn.server.nodemanager.DeletionService: Exception during > execution of task in DeletionService > java.lang.NullPointerException > at > org.apache.hadoop.fs.FileContext.fixRelativePart(FileContext.java:274) > at org.apache.hadoop.fs.FileContext.delete(FileContext.java:761) > at > org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor.deleteAsUser(DefaultContainerExecutor.java:457) > at > org.apache.hadoop.yarn.server.nodemanager.DeletionService$FileDeletionTask.run(DeletionService.java:293) > at > java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) > at java.util.concurrent.FutureTask.run(FutureTask.java:266) > at > java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$201(ScheduledThreadPoolExecutor.java:180) > at > java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:293) > at > java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) > at > java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) > at java.lang.Thread.run(Thread.java:745) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
