Chris Nauroth commented on HADOOP-9439: --------------------------------------- Hi, Colin. I had filed HADOOP-9312 for a potential memory leak around the lazy initialization of {{emptyGroups}}. From my quick scan of the patch here, it looks like this will fix it (at least for the non-Windows codebase). Do you agree? If so, I will relate the 2 jiras, or perhaps file a new jira for porting this patch to the Windows version.
