Andrey Stepachev updated HBASE-13004: ------------------------------------- Status: Patch Available (was: Open) > Make possible to explain why HTU.waitFor fails > ---------------------------------------------- > > Key: HBASE-13004 > URL: https://issues.apache.org/jira/browse/HBASE-13004 > Project: HBase > Issue Type: Bug > Components: test > Affects Versions: 2.0.0 > Reporter: Andrey Stepachev > Assignee: Andrey Stepachev > Priority: Minor > Attachments: HBASE-13004.patch > > > HBaseTestingUtility has good methods for waiting conditions, but with one > drawback, when waitfor fails, there is no way to explain what happened > (fail() called from internals and that is not very easy to intercept and > explain state of failure). > That would be great to have enhanced Predicate which can explain state after > it failed to wait for. > That can looks like > {code} > HUT.waitFor(10000, new ExplainingPredicate() { > boolean evaluate() { > ... some evaluation code > } > String explain() { > ... generate brief explanation of what to be expected, but not happened > } > } > {code} -- This message was sent by Atlassian JIRA (v6.3.4#6332)
