Kitti Nanasi commented on HDFS-14061: ------------------------------------- Thanks for the comment [~ayushtkn]! You are right, failing the policy setting might be too harsh. Why I wanted to do that was because when setting the policy and writing to the folder, the error message we get is quite misleading. But I think if that message is corrected, it will be fine, so I raised [HDFS-14187|https://issues.apache.org/jira/browse/HDFS-14187] for that. And in patch 002 I fixed your comments. > Check if the cluster topology supports the EC policy before setting, enabling > or adding it > ------------------------------------------------------------------------------------------ > > Key: HDFS-14061 > URL: https://issues.apache.org/jira/browse/HDFS-14061 > Project: Hadoop HDFS > Issue Type: Improvement > Components: erasure-coding, hdfs > Affects Versions: 3.1.1 > Reporter: Kitti Nanasi > Assignee: Kitti Nanasi > Priority: Major > Attachments: HDFS-14061.001.patch, HDFS-14061.002.patch > > > HDFS-12946 introduces a command for verifying if there are enough racks and > datanodes for the enabled erasure coding policies. > This verification could be executed for the erasure coding policy before > enabling, setting or adding it and a warning message could be written if the > verify fails, or the policy setting could be even failed in this case. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
