[jira] [Commented] (HDFS-8065) Erasure coding: Support truncate at
striped group boundary
[ https://issues.apache.org/jira/browse/HDFS-8065?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15376304#comment-15376304 ]

--------------------------------
Hi, [~drankye], [~umamaheswararao], [~zhz]
IMHO, truncate on block group boundary can be supported without much effort compare to the partial stripe case, which(latter) will be addressed via HDFS-7622 jira. Could you please help me in pushing this jira for {{3.0.0-alpha1}} release. Handling of partial stripe logic is needed for lease recovery, truncation, hflush cases which I feel together can be implemented based on the HDFS-7661 design discussions. Welcome thoughts?
