Xiao Chen commented on HADOOP-15450:
------------------------------------

Thanks all for the work here.

As [~gabor.bota] found out in an offline review, it seems the whitespace and checkstyle are
not addressed before committing. I understand everyone is busy, but this is a bad practice
and should not be followed. :)

This was fine before, but now it incurs heavy I/O due to introduction of fsync() in the code.
