Sunil G commented on YARN-2729: ------------------------------- Yes [~rohithsharma]. With this, child class will have the capability to clean up stuffs which can be done after time is cancelled. So {{shExec.destroy()}} can be called from {{cleanUp()}} which is implemented/overridden in {{ScriptBasedNodeLabelsProvider}} > Support script based NodeLabelsProvider Interface in Distributed Node Label > Configuration Setup > ----------------------------------------------------------------------------------------------- > > Key: YARN-2729 > URL: https://issues.apache.org/jira/browse/YARN-2729 > Project: Hadoop YARN > Issue Type: Sub-task > Components: nodemanager > Reporter: Naganarasimha G R > Assignee: Naganarasimha G R > Attachments: YARN-2729.20141023-1.patch, YARN-2729.20141024-1.patch, > YARN-2729.20141031-1.patch, YARN-2729.20141120-1.patch, > YARN-2729.20141210-1.patch, YARN-2729.20150309-1.patch, > YARN-2729.20150322-1.patch, YARN-2729.20150401-1.patch, > YARN-2729.20150402-1.patch, YARN-2729.20150404-1.patch, > YARN-2729.20150517-1.patch, YARN-2729.20150830-1.patch, > YARN-2729.20150925-1.patch, YARN-2729.20151015-1.patch, > YARN-2729.20151019.patch, YARN-2729.20151310-1.patch, > YARN-2729.20151310-2.patch > > > Support script based NodeLabelsProvider Interface in Distributed Node Label > Configuration Setup . > Miscellaneous Issues : > # In configurationNodeLabelsProvider instead of taking multiple labels from > single configuration, we need to support exclusive configuration for > partition (single label). > # Proper logging when registration of Node Fails > # Classloader was not getting reset from custom class loader in > TestConfigurationNodeLabelsProvider.java which could make test cases fail in > certain conditions > # In ResourceTrackerService we need to consider distributed configuration > only when node labels are enabled. leads to lots of logs in certain conditions > # NodeLabelsProvider needs to be a interface rather than abstract class -- This message was sent by Atlassian JIRA (v6.3.4#6332)
