Subject [jira] [Created] (HIVE-3857) HiveHistoryViewer concurrency problem
Date Fri, 04 Jan 2013 09:06:15 GMT
qiangwang created HIVE-3857:
-------------------------------

             Summary: HiveHistoryViewer concurrency problem
                 Key: HIVE-3857
                 URL: https://issues.apache.org/jira/browse/HIVE-3857
             Project: Hive
          Issue Type: Bug
          Components: Logging
            Reporter: qiangwang
            Priority: Minor


new HiveHistoryViewer() throws ConcurrentModificationException when called concurrently by
several threads.

According to the stacktrace, HiveHistory.parseLine use "private static Map<String, String>
parseBuffer" to store parsed data and this finally caused the exception.

I don't know why a static buffer rather than a local buffer is used!
