-------------------------------
Hi Konstantin,
The "power platform" means IBM power system/server and the Linux OS for power
has some differences from Linux OS for x86 system. In the test, 'BLOCK_SIZE =
4096' does not mean the HDFS block size is 4096, but mean the operating system
page size is 4096. The page size of operating systems are different, so we
should not hardcode the page size in the test. The correct way is to get the
page size using
'NativeIO.POSIX.getCacheManipulator().getOperatingSystemPageSize()' instead.
> TestFileAppendRestart hardcode block size without considering native OS

> TestFileAppendRestart hardcode block size with 'BLOCK_SIZE = 4096', however
> it's incorrect on some platforms. For example, on power platform, the correct
> value is 65536.
