----------------------------------------
Summary: Ozone: Handle larger file sizes for OzoneOutputStream &
OzoneInputStream
Key: HDFS-12767
URL: https://issues.apache.org/jira/browse/HDFS-12767
Project: Hadoop HDFS
Issue Type: Sub-task
Components: ozone
Affects Versions: HDFS-7240
Reporter: Mukul Kumar Singh
Assignee: Mukul Kumar Singh
Priority: Major
Fix For: HDFS-7240
This is based on [[email protected]]'s comments on HDFS-7240. This jira will
add capabilities to OzoneOutputStream and OzoneInputStream stream to handle
larger file sizes. This jira will also address other Streams related review
comments.
OzoneOutputStream
Implement StreamCapabilities and declare that hsync/hflush are not
supported.
Unless there is no limit on the size of a PUT request/multipart uploads are
supported, consider
having the stream's write(int) method fail when the limit is reached.
That way, things will at least fail fast.
after close, set backupStream = null.
flush() should be a no-op if called on a closed stream, so if (closed)
return
write() must fail if called on a closed stream,
Again, OzoneException -> IOE translation which could/should be eliminated.
OzoneInputStream
1) You have chosen an interesting solution to the "efficient seek" problem
here: D/L the entire file and then seek around. While this probably works for
the first release, larger files will have problems in both disk space and size
of
2) Again, OzoneException -> IOE translation which could/should be eliminated.
