Subject [jira] [Commented] (HBASE-5887) Make TestAcidGuarantees usable for system testing.
Date Fri, 27 Apr 2012 00:10:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5887?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13263264#comment-13263264

Jonathan Hsieh commented on HBASE-5887:

Yes.  When you use the tool wrapper stuff you get parsers for that for free.

You could do something like this to override any of these values:

$ hbase org.apache.hadoop.hbase.TestAcidGuarantees -Dmillis=60000 -DnumWriters=25 -DnumGetters=10
-DnumScanners=5 -DnumUniqueRows=5

I should probably add a '-h' or '-?' option to prompt usage instructions.

> Currently, the TestAcidGuarantees run via main() will always abort with an NPE because
it digs into a non-existant HBaseTestingUtility for a flusher thread.  We should tool this
up so that it works properly from the command line.  This would be a very useful long running
test when used in conjunction with fault injections to verify row acid properties.
