[jira] Created: (HDFS-1590) Decommissioning never ends when node to decommission has blocks that are under-replicated and cannot be replicated to the expected level of replication
Decommissioning never ends when node to decommission has blocks that are under-replicated and cannot be replicated to the expected level of replication --- Key: HDFS-1590 URL: https://issues.apache.org/jira/browse/HDFS-1590 Project: Hadoop HDFS Issue Type: Bug Components: name-node Affects Versions: 0.20.2 Environment: Linux Reporter: Mathias Herberts Priority: Minor On a test cluster with 4 DNs and a default repl level of 3, I recently attempted to decommission one of the DNs. Right after the modification of the dfs.hosts.exclude file and the 'dfsadmin -refreshNodes', I could see the blocks being replicated to other nodes. After a while, the replication stopped but the node was not marked as decommissioned. When running an 'fsck -files -blocks -locations' I saw that all files had a replication of 4 (which is logical given there are 4 DNs), but some of the files had an expected replication set to 10 (those were job.jar files from M/R jobs). I ran 'fs -setrep 3' on those files and shortly after the namenode reported the DN as decommissioned. Shouldn't this case be checked by the NameNode when decommissioning a node? I.e considere a node decommissioned if either one of the following is true for each block on the node being decommissioned: 1. It is replicated more than the expected replication level. 2. It is replicated as much as possible given the available nodes, even though it is less replicated than expected. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
