HiveHistoryViewer concurrency problem
Qiang Wang 2013-01-04, 08:28
new HiveHistoryViewer() throws ConcurrentModificationException when called
concurrently by several threads.

According to the stack trace, HiveHistory.parseLine use *private static
Map<String, String> parseBuffer* to store parsed data and this caused the
exception.

I don't know why a static buffer rather than a local buffer is used!
Anybody have an idea about this?
