Subject [jira] [Commented] (FLINK-5372) Fix RocksDBAsyncSnapshotTest.testCancelFullyAsyncCheckpoints()
Date Tue, 17 Jan 2017 03:14:26 GMT

    [ https://issues.apache.org/jira/browse/FLINK-5372?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15824885#comment-15824885
] 

Syinchwun Leo commented on FLINK-5372:
--------------------------------------

When I run RocksDBStateBackend's test alone, it is OK. But when running Flink's whole test,
it will be locked like the following:   
-------------------------------------------------------
 T E S T S
-------------------------------------------------------
Running org.apache.flink.contrib.streaming.state.RocksDBInitResetTest

> The test is currently {{@Ignored}}. We have to change {{AsyncCheckpointOperator}} to
make sure that we can run fully asynchronously. Then, the test will still fail because the
canceling behaviour was changed in the meantime.
