sam liu commented on HDFS-7630:
-------------------------------
Arpit,
Not all such hard-coding will cause failure and the patch is mainly to remove
the hard-coding. But sometimes the hard-coding could cause failure. For
example, without patch HDFS-7585, test TestEnhancedByteBufferAccess will fail
on power platform. In the tests, the size of BLOCK_SIZE is usually set as 4096
and it just equals to the default page size of x86 Linux operating system, but
on power Linux operating system the default page size is 65536. As HDFS is
based on operating system, it might be better the unit tests could consider the
differences of operating systems.
Thanks!

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