Siyao Meng updated HDDS-11322:
------------------------------
Description:
ECKeyOutputStream extends KeyOutputStream, but EC keys does not support hsync()
as there are known issues with that: HDDS-8932
(Even if we add EC hsync support in the future, there would be significant
overhead with small writes due to striping and parity calc. But that is a
different topic.)
This jira prevents hsync() and hflush() from being called on ECKeyOutputStream
by throwing NotImplementedException.
