Description

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!
