These issues were addressed in the new API > (MAPREDUCE-1423), but the old class was not fixed. > The main issue the JIRA refers to is a performance problem. However, IMO > there is a more serious problem which is a thread-safety issue (rackToNodes) > which was fixed alongside. > What is the policy on addressing issues in the old API? Can we backport this > to the old class? -- This message is automatically generated by JIRA.
