> libhdfs uses the deprecated property {{dfs.block.size}}.  It would be better for libhdfs
to use the FileSystem#getDefaultBlockSize API instead.
> This API has two advantages:
> 1. It uses the new, non-deprecated {{dfs.blocksize}} property
> 2. It handles string escapes like 'M' for 'megabytes' etc. which can appear in {{dfs.blocksize}}
and {{dfs.block.size}}
