[jira] [Created] (MAPREDUCE-6616) Fail to create jobhistory file if there are some multibyte characters in the job name

Akira AJISAKA created MAPREDUCE-6616:
----------------------------------------

             Summary: Fail to create jobhistory file if there are some multibyte characters in the job name
                 Key: MAPREDUCE-6616
                 URL: https://issues.apache.org/jira/browse/MAPREDUCE-6616
             Project: Hadoop Map/Reduce
          Issue Type: Bug
          Components: jobhistoryserver
            Reporter: Akira AJISAKA


When creating jobhistory file, job name is trimmed within 50 characters by default, and the name is URL-encoded *after* the job name is trimmed. Therefore, if there are some multibyte characters in the job name, the encoded job name can be longer than 50 characters. Eventually it can break the limit of the file name (Usually 255 characters).
