Rakesh R commented on HDFS-7622:
--------------------------------
As per the analysis there are cases of partial block stripes has to be handled,
which is similar to the case of recovery on partial stripe (which could be
triggered by a {{#hflush}} call) and {{#hflush}} HDFS-7661. While implementing
the truncation of partial block stripes, it is touching the
{{RecoveryTaskStriped#recover()}} part, so I feel to revisit this jira once
HDFS-7661 discussion/logic is settle down.
It would be great if someone could help me in pushing HDFS-8065 block group
boundary truncation jira, which I think can be supported now.
