[jira] [Updated] (MAPREDUCE-7129) Cannot assign container
Container: maps.isEmpty=true
[ https://issues.apache.org/jira/browse/MAPREDUCE-7129?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stefanlee updated MAPREDUCE-7129:
---------------------------------
Environment: (was: we have many mapreduce applications without reduce task, and we found a lot of *Cannot assign container Container: maps.isEmpty=true* information in MRAppMaster log, they are unused containers in *scheduledRequests.assign* and released by RM, and MRAppMaster will hang 2 mimute at *getResource* ,i doubt if it's inconsistent between *ask* and *maps*?)
