Hudson commented on YARN-541: ----------------------------- FAILURE: Integrated in Hadoop-Mapreduce-trunk #1487 (See [https://builds.apache.org/job/Hadoop-Mapreduce-trunk/1487/]) YARN-541. getAllocatedContainers() is not returning all the allocated containers (bikas) (bikas: http://svn.apache.org/viewcvs.cgi/?root=Apache-SVN&view=rev&rev=1502906) * /hadoop/common/trunk/hadoop-yarn-project/CHANGES.txt * /hadoop/common/trunk/hadoop-yarn-project/hadoop-yarn/hadoop-yarn-client/src/main/java/org/apache/hadoop/yarn/client/api/impl/AMRMClientImpl.java > getAllocatedContainers() is not returning all the allocated containers > ---------------------------------------------------------------------- > > Key: YARN-541 > URL: https://issues.apache.org/jira/browse/YARN-541 > Project: Hadoop YARN > Issue Type: Bug > Components: resourcemanager > Affects Versions: 2.0.3-alpha > Environment: Redhat Linux 64-bit > Reporter: Krishna Kishore Bonagiri > Assignee: Bikas Saha > Priority: Blocker > Fix For: 2.1.0-beta > > Attachments: AppMaster.stdout, YARN-541.1.patch, > yarn-dsadm-nodemanager-isredeng.out, yarn-dsadm-resourcemanager-isredeng.out > > > I am running an application that was written and working well with the > hadoop-2.0.0-alpha but when I am running the same against 2.0.3-alpha, the > getAllocatedContainers() method called on AMResponse is not returning all the > containers allocated sometimes. For example, I request for 10 containers and > this method gives me only 9 containers sometimes, and when I looked at the > log of Resource Manager, the 10th container is also allocated. It happens > only sometimes randomly and works fine all other times. If I send one more > request for the remaining container to RM after it failed to give them the > first time(and before releasing already acquired ones), it could allocate > that container. I am running only one application at a time, but 1000s of > them one after another. > My main worry is, even though the RM's log is saying that all 10 requested > containers are allocated, the getAllocatedContainers() method is not > returning me all of them, it returned only 9 surprisingly. I never saw this > kind of issue in the previous version, i.e. hadoop-2.0.0-alpha. > Thanks, > Kishore > -- This message is automatically generated by JIRA.
