--------------------------------------------
HI [~virajith], ok, I got ur case. Since the schemes are different, it make
sense to configure separately. However I have a question, is there a case your
configured cluster name is different than fs.defaultFS ? In both of your case,
you may end up configuring 'clustername' for default mounttable name right?
Anyway just supporting configurable default mount-table name should be ok with
me. You may want to add your recommendation of configuring this class for this
special cases for users? ViewFSOverloadScheme.md
I have dropped few minor/nit comments in PR.

> Key: HDFS-15436
> URL: https://issues.apache.org/jira/browse/HDFS-15436
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: viewfs, viewfsOverloadScheme
> Reporter: Virajith Jalaparti
> Assignee: Virajith Jalaparti
> Priority: Major
>
> Currently, if no authority is provided and the scheme of the Path is doesn't
> match the scheme of the {{fs.defaultFS}} , the mount table used by
> ViewFileSystem to resolve this path is {{default}}.
> This breaks accesses to path like {{hdfs:///foo/bar}} (without any authority)
> when the following configurations are used:
> (1) {{fs.defaultFS}} = {{viewfs://clustername/}}
> (2) {{fs.hdfs.impl =
> org.apache.hadoop.fs.viewfs.ViewFileSystemOverloadScheme}}
> This JIRA proposes to add a new configuration
> {{fs.viewfs.mounttable.default.name.key}} which is used to get the name of
> the cluster/mount table when the authority is missing in cases like the
> above. If not set, the string {{default}} will be used as today.
