[jira] [Commented] (HDFS-12144) Ozone: KSM: Cleanup of keys in KSM
for failed clients
[ https://issues.apache.org/jira/browse/HDFS-12144?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16088267#comment-16088267 ]
Chen Liang commented on HDFS-12144:
-----------------------------------
I read through the comments in HDFS-12123 discussion. Actually I think I wrote that original TODO comment in the code, and as the follow-up, HDFS-11886 was filed. So this JIRA seems to be a duplicate of HDFS-11886? (Please feel free to comment/edit HDFS-11886 if there is anything you want to add also).
