             Summary: [hsync] Block ECKeyOutputStream from calling hsync()
                 Key: HDDS-11322
                 URL: https://issues.apache.org/jira/browse/HDDS-11322
             Project: Apache Ozone
          Issue Type: Sub-task
          Components: Ozone Client
            Reporter: Siyao Meng
            Assignee: Siyao Meng


ECKeyOutputStream extends KeyOutputStream, but EC keys does not support hsync() 
as there are known issues with that. (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.
