Tsz Wo (Nicholas), SZE commented on HDFS-741:
---------------------------------------------
{code}
+ int readBytes = is.read(toRead, 0, tenth);
+ assertEquals("Should've get more bytes", tenth, readBytes);
{code}
Why expecting (tenth == readBytes)? java.io.DataInputStream.read(..) may read some number
of bytes up to the given length but not necessary all the bytes, i.e. it is okay if we have
(0 < readBytes <= tenth).
> 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.
