Kihwal Lee reassigned HDFS-3087: -------------------------------- Assignee: Kihwal Lee > Decomissioning on NN restart can complete without blocks being replicated > ------------------------------------------------------------------------- > > Key: HDFS-3087 > URL: https://issues.apache.org/jira/browse/HDFS-3087 > Project: Hadoop HDFS > Issue Type: Bug > Components: name-node > Affects Versions: 0.23.0, 0.24.0 > Reporter: Kihwal Lee > Assignee: Kihwal Lee > Priority: Critical > Fix For: 0.23.0, 0.24.0, 0.23.2, 0.23.3 > > > If a data node is added to the exclude list and the name node is restarted, > the decomissioning happens right away on the data node registration. At this > point the initial block report has not been sent, so the name node thinks the > node has zero blocks and the decomissioning completes very quick, without > replicating the blocks on that node. -- This message is automatically generated by JIRA.
