Hairong Kuang commented on HDFS-741:
------------------------------------

Cos, could you please try verifying the whole file instead of the newly hflushed data. This way we can identify if this is a bug of seek or a bug of hflush.

> 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.
