Yi Liu commented on HDFS-7740: ------------------------------ Thanks [~shv] for your comments. I will address them later, currently I'am on holiday for Chinese traditional new year, so there is some delay for the update. {quote} I don't think your new tests will work with the ones existing in TestFileTruncate, because you are restarting the whole cluster {quote} Oh, not noticed these before :) I thought if I use a different Mini DFS Cluster with different ports, then they will not affect each other. {quote} I would propose to put your new cases into a new file It would be good to start the cluster once in @BeforeClass I think this is possible as you do not need to reformat the cluster after each test {quote} Good idea, I will move them to a new class, and then we can use @BeforeClass. Yes, we don't need to reformat the cluster. {quote} With DNs restarting one way to accelerate test running time is to shorten heartbeats, as we did in TestFileTruncate. {quote} We already use the short hearbeats for the new test. > Test truncate with DataNodes restarting > --------------------------------------- > > Key: HDFS-7740 > URL: https://issues.apache.org/jira/browse/HDFS-7740 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: test > Affects Versions: 2.7.0 > Reporter: Konstantin Shvachko > Assignee: Yi Liu > Fix For: 2.7.0 > > Attachments: HDFS-7740.001.patch > > > Add a test case, which ensures replica consistency when DNs are failing and > restarting. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
