             Summary: Improve performance of TestHBaseFsck
                 Key: HBASE-12740
                 URL: https://issues.apache.org/jira/browse/HBASE-12740
             Project: HBase
          Issue Type: Bug
          Components: util
            Reporter: Jurriaan Mous
            Assignee: Jurriaan Mous


TestHBaseFsck performs poor on my machine. It crashes because the threads reach the 2000 thread limit on my machine. Looking at the code a lot of optimization is possible and some API calls are used wrong. A lot of Admin instances are created and never closed, lots of Tables are not closed, ThreadPoolExecutors are not shut down and an unlimited thread pool which does not recycle threads.
