Shashikant Banerjee updated HDDS-322:
-------------------------------------
Description:
Currently, ChunkOutputStream allocate a chunk size buffer to cache client data.
The idea here is to allocate the buffer in ChunkGroupOutputStream and pass it
to underlying ChunkOutputStream so as to make reclaiming of the uncommitted
leftover data in the buffer and reallocating to next Block while handling
CLOSE_CONTAINER_EXCEPTION in ozone client becomes simpler. This Jira will also
add the code to close the underlying ChunkOutputStream as soon as the complete
block data is written.
This Jira will also modify the PutKey response to contain the committed block
length to ozone client to do some validation checks.
