It's true that HDFS (and Hadoop generally) doesn't currently have a
ByteBuffer-based pread API. There is a JIRA open for this issue,
HDFS-3246.
I do not know if implementing a ByteBuffer API for pread would be as
big of a performance gain as implementing it for regular read. One
issue is that wh
There is ByteBuffer read API for sequential read in CDH4.3.1,
example:public synchronized int read(final ByteBuffer buf) throws
IOException API. But there is not ByteBuffe read API for pread.
Why don't support ByteBuffer read API for pread in CDH4.3.1?
Thanks,
