[jira] [Updated] (ACCUMULO-2695) Failure while running conditional
RW test w/ agitation
[ https://issues.apache.org/jira/browse/ACCUMULO-2695?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Keith Turner updated ACCUMULO-2695:
-----------------------------------
Attachment: BugTest.java
Attached {{BugTest.java}} this test will reproduce the problem. Its a copy of some code from the Conditional random walk test slightly modified to run against MAC. The test also contains a simple agitator for MAC.
The test takes 500 seconds to run on my workstation, not something I want to add to the build. The test case is covered by random walk. Decided to add the test to the ticket instead of throw it away. Using this test I isolated the problem and have a patch underway.
