Thus resulting in either of the 2 > counter values to be not satisfying the condition and getting in an infinite > loop and hence timing out the test eventually. > Possible Fixes: > - Write better test(That would pass under all conditions). > - Maybe UT instead of IT? > Possible fix to better the test would be preferable and UT as the last resort. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
