Yiqun Lin commented on HDFS-13214: ---------------------------------- Thanks for the review, [~elgoiri]. {quote} Move the old related unit tests to this new unit test {quote} Do you mean we can combine the test {{TestNamenodeHeartbeat#testHearbeat}} in new unit test? {quote} One concern nowadays is that the amount of unit tests using MiniDFSCluster is getting very large and it is pretty expensive for the build. {quote} It's a good point. One way I am thinking that we can construct some simulated NN/DNs and don't start real nodes/clusters. If there are some test cases which need many namespaces, this will spend a lot of time to start. The review comments for v02 patch have all addressed.
