--------------------------------
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?
