>                 URL: https://issues.apache.org/jira/browse/HDFS-10610
>             Project: Hadoop HDFS
>          Issue Type: Bug
>    Affects Versions: 2.8.0
>            Reporter: Eric Badger

> Instantiating a new DfsClient used to add hdfs-site.xml as a resource in 2.7, but that
compatibility has been broken in 2.8. This only accidentally worked in 2.7, since DfsClient
would load HdfsConstants, which would in turn create the static IO_FILE_BUFFER_SIZE, which
would instantiate an HdfsConfiguration, which would finally add hdfs-site.xml. 
> In 2.8, IO_FILE_BUFFER_SIZE no longer exists in HdfsConstants.java and so this no longer
works out of coincidence.
