Subject [jira] [Created] (MAPREDUCE-5819) Binary token merge should be done once in TokenCache#obtainTokensForNamenodesInternal()
Date Wed, 02 Apr 2014 22:43:19 GMT
Ted Yu created MAPREDUCE-5819:
---------------------------------

             Summary: Binary token merge should be done once in TokenCache#obtainTokensForNamenodesInternal()
                 Key: MAPREDUCE-5819
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-5819
             Project: Hadoop Map/Reduce
          Issue Type: Improvement
            Reporter: Ted Yu
            Assignee: Ted Yu
            Priority: Minor


Currently mergeBinaryTokens() is called by every invocation of obtainTokensForNamenodesInternal(FileSystem,
Credentials, Configuration) in the loop of obtainTokensForNamenodesInternal(Credentials, Path[],
Configuration).

This can be simplified so that mergeBinaryTokens() is called only once in obtainTokensForNamenodesInternal(Credentials,
Path[], Configuration).
