public class TestAsyncProcessWithRegionException extends Object
The purpose of this test is to make sure the region exception won't corrupt the results of batch. The prescription is shown below. 1) honor the action result rather than region exception. If the action have both of true result and region exception, the action is fine as the exception is caused by other actions which are in the same region. 2) honor the action exception rather than region exception. If the action have both of action exception and region exception, we deal with the action exception only. If we also handle the region exception for the same action, it will introduce the negative count of actions in progress. The AsyncRequestFuture#waitUntilDone will block forever. This bug can be reproduced by real use case. see TestMalformedCellFromClient(in branch-1.4+). It uses the batch of RowMutations to present the bug. Given that the batch of RowMutations is only supported by branch-1.4+, perhaps the branch-1.3 and branch-1.2 won't encounter this issue. We still backport the fix to branch-1.3 and branch-1.2 in case we ignore some write paths.
