Subject [jira] [Updated] (HBASE-12740) Improve performance of TestHBaseFsck
Date Tue, 23 Dec 2014 14:09:14 GMT

     [ https://issues.apache.org/jira/browse/HBASE-12740?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel

Jurriaan Mous updated HBASE-12740:
    Attachment: HBASE-12740-v2.patch

Properly close region in HbaseFsckRepair. (It was not closing its wall) This shaves off 2m40
of runtime of the test and saves a lot of threads.

> 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.
