Manoj Govindassamy updated HDFS-11718: -------------------------------------- Description: This is a clone bug of HDFS-11644 to provide a quick fix while a proper fix is being discussed and developed. The quick fix here would be to just turn {{DFSStripedOutputStream#hsync()/hflush()}} as a no-op instead of throwing UnsupportedOperationException. @Override public void hflush() { throw new UnsupportedOperationException(); } @Override public void hsync() { throw new UnsupportedOperationException(); } For more details please refer to the comments in HDFS-11644. was: FSDataOutputStream#hsync checks if a stream implements Syncable, and if so, calls hsync. Otherwise, it just calls flush. This is used, for instance, by YARN's FileSystemTimelineWriter. DFSStripedOutputStream extends DFSOutputStream, which implements Syncable. However, DFSStripedOS throws a runtime exception when the Syncable methods are called. We should refactor the inheritance structure so DFSStripedOS does not implement Syncable. > DFSStripedOutputStream hsync/hflush should not throw > UnsupportedOperationException > ---------------------------------------------------------------------------------- > > Key: HDFS-11718 > URL: https://issues.apache.org/jira/browse/HDFS-11718 > Project: Hadoop HDFS > Issue Type: Bug > Components: erasure-coding > Affects Versions: 3.0.0-alpha1 > Reporter: Manoj Govindassamy > Assignee: Manoj Govindassamy > Priority: Blocker > Labels: hdfs-ec-3.0-must-do > > This is a clone bug of HDFS-11644 to provide a quick fix while a proper fix > is being discussed and developed.
