Konstantin Boudnik updated HDFS-741:
------------------------------------
Attachment: HDFS-741.patch
It seems that you're right. However, the point is still valid although is
slightly different: I'm able to read >0 bytes after seek. However, they content
is filled with '0' rather then with something the test is writing into the
file. Slightly modified version of the test to demonstrate just that.
> TestHFlush test doesn't seek() past previously written part of the file

> As a part of the test scenario a file is being written, 10th of the total
> length in a time. Then a reader is opened to read what has been just written
> and hflush'ed. However, it always starts reading from the 0 position of the
> file and doesn't seek to the start of the portion written last.
