TestSCMNodeMetrics was a legitimate failure, I have fixed it. TestSecureContainerServer.testClientServerRatisGrpc() was failing on trunk, but has now been fixed. TestBlockOutputStreamWithFailures.testWatchForCommitDatanodeFailure() seems flaky. It has passed and failed a few times locally. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.

The first, is effectively the liveliness of the > node, with the following states. This is largely what is in place now: > HEALTHY > STALE > DEAD > The second is the node operational state: > IN_SERVICE > DECOMMISSIONING > DECOMMISSIONED > ENTERING_MAINTENANCE > IN_MAINTENANCE > That means the overall total number of states for a node is the cross-product > of the two above lists, however it probably makes sense to keep the two > states seperate internally. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
