Review comment:
Please add `ozone.client.checksum.combine.mode` config to
ozone-default.xml file.

Review comment:
Please move the `if (keyName.length() == 0) {` validation inside
`OzoneClientUtils.getFileChecksumWithCombineMode()` so that both o3fs and ofs
will have the check.
Also, Please make a `Preconditions.checkArgument(length >= 0); `check.
