Arpit Agarwal commented on HDFS-7630:
-------------------------------------
Hi Sam, I understand your concern but I think for these tests it is not an
issue. The tests should have no dependency on OS page size.
I believe the choice of 4096 as the block size was arbitrary and it being the
same as the default page size on x86/x64 is just a coincidence.

> 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.
