Ayush Saxena commented on HDFS-14803:
-------------------------------------
[~hemanthboyina] The truncate return response is based on following logic :
{noformat}
Returns:
true if client does not need to wait for block recovery, false if client needs
to wait for block recovery.
{noformat}
Not whether truncated or not, That is why onBlockBoundary is used for return
response. Seems the behavior is correct only, Since you have one block and you
aren't truncating at boundary, You need to wait for recovery, hence false.
Please check again once.
> Truncate return value was wrong
