It does not make sense the > EMPTY_START_ROW as splitKey (since the region with the empty start key is > implicit), but it should not cause the HMaster to abort. > The abort happens because it tries to bulk assign the same region twice and > then runs into race conditions with ZK. > The same would (presumably) happen when two identical split keys are passed, > but the client blocks that. The simplest solution here is to also block > passed null or EMPTY_START_ROW as split key by the client. -- This message is automatically generated by JIRA.
