[jira] [Created] (YARN-4178) [storage implementation] app id as string can cause incorrect ordering

Sangjin Lee created YARN-4178:
---------------------------------

             Summary: [storage implementation] app id as string can cause incorrect ordering
                 Key: YARN-4178
                 URL: https://issues.apache.org/jira/browse/YARN-4178
             Project: Hadoop YARN
          Issue Type: Sub-task
          Components: timelineserver
    Affects Versions: YARN-2928
            Reporter: Sangjin Lee


Currently the app id is used in various places as part of row keys and in column names. However, they are treated as strings for the most part. This will cause a problem with ordering when the id portion of the app id rolls over to the next digit.

For example, "app_1234567890_100" will be considered *earlier* than "app_1234567890_99". We should correct this.
