Use a thread-local rather than static ENCODER/DECODER variables in Text for synchronization
-------------------------------------------------------------------------------------------

                 Key: HADOOP-3863
                 URL: https://issues.apache.org/jira/browse/HADOOP-3863
             Project: Hadoop Core
          Issue Type: Bug
          Components: mapred
    Affects Versions: 0.18.0
            Reporter: Arun C Murthy
            Assignee: Arun C Murthy
            Priority: Critical
             Fix For: 0.19.0


Text.{ENCODER|DECODER} are static variables which need to be synchronized in Text.{read|write}String;
given that lots of RPC code calls Text.{read|write}String the contention for this lock shows
up very significantly on large clusters.
