Kaijie Chen updated HDDS-6400:
------------------------------
Description:
Refactor ECKeyOutputStream to make the code cleaner.
Reuse code when writing the last stripe or rewriting failed stripes.
The changes includes:
# handleDataWrite() has been changed to handleWrite(),
it will check strip full and call encodeAndWriteParityCells().
# checkAndWriteParityCells() has been changed to encodeAndWriteParityCells(),
and it can be reused to encode partial stripe in close().
# handleParityWrites() has seperated generateParityCells(),
it can be reused in rewriteStripeToNewBlockGroup().
# handleFailedStreams() has been changed to excludePipelineAndFailedDN(),
it will exclude both failed pipeline and failed datanodes.
