[jira] [Updated] (MAPREDUCE-7308) Containers never get reused as
containersToReuse map gets cleared on makeRemoteRequest
[ https://issues.apache.org/jira/browse/MAPREDUCE-7308?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Bilwa S T updated MAPREDUCE-7308:
---------------------------------
Description: In RMContainerReuseRequestor whenever containerAssigned is called it checks if allocated container can be reused. This always returns false as the map is getting cleared on makeRemoteRequest. I think container can be removed from containersToReuse map once its used. (was: In RMContainerReuseRequestor whenever containerAssigned is called it checks if allocated container can be reused. This always returns false as the map is getting cleared on makeRemoteRequest. I think there is no need to clear the map as container will be removed from containersToReuse map once its used.)
