Erik Krogen created HDFS-12004: ---------------------------------- Summary: Namenode UI continues to list DNs that have been removed from include and exclude Key: HDFS-12004 URL: https://issues.apache.org/jira/browse/HDFS-12004 Project: Hadoop HDFS Issue Type: Bug Affects Versions: 2.3.0 Reporter: Erik Krogen Priority: Minor
Initially in HDFS, after a DN was decommission and subsequently removed from the exclude file (thus removing all references to it), it would still appear in the NN UI as a "dead" node until the NN was restarted. In HDFS-1773, discussion about this was had, and it was decided that the web UI should not show these nodes. However when HDFS-5334 went through and the NN web UI was reimplemented client-side, the behavior reverted back to pre-HDFS-1773, and dead+decommissioned nodes once again showed in the dead list. This can be operationally confusing for the same reasons as discussed in HDFS-1773. I would like to open this discussion to determine if the regression was intentional or if we should carry forward the logic implemented HDFS-1773 into the new UI. -- This message was sent by Atlassian JIRA (v6.4.14#64029) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
