Anupam Seth updated MAPREDUCE-4020: ----------------------------------- Attachment: MAPREDUCE-4020-branch-23.patch Seems like the Java object structure is just fine. The JSON converter is having trouble because of circularl list references. Attaching patch to work around issue by creating a list class encapsulating the ArrayList of queueInfo objects. Kindly review. > Web services returns incorrect JSON for deep queue tree > ------------------------------------------------------- > > Key: MAPREDUCE-4020 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-4020 > Project: Hadoop Map/Reduce > Issue Type: Bug > Components: mrv2, webapps > Affects Versions: 0.23.1 > Reporter: Jason Lowe > Assignee: Anupam Seth > Attachments: MAPREDUCE-4020-branch-23.patch, testcase.patch > > > When the capacity scheduler is configured for more than two levels of queues, > the web services API returns incorrect JSON for the subQueues field of some > parent queues. The "subQueues" field for parent queues should always be an > array, but sometimes the field appears multiple times for a queue and as what > looks like a CapacityQueueInfo object instead of an array. Besides the > sometimes-an-array-sometimes-not problem, parsing the result into a JSON > object causes all but the last "subQueues" field to be discarded since they > are overwritten by subsequent fields with the same name. -- This message is automatically generated by JIRA.
