------------------------------------------
Summary: ViewFsOverloadScheme should work when -fs option pointing
to remote cluster without mount links
Key: HDFS-15464
URL: https://issues.apache.org/jira/browse/HDFS-15464
Project: Hadoop HDFS
Issue Type: Sub-task
Components: viewfsOverloadScheme
Affects Versions: 3.2.1
Reporter: Uma Maheswara Rao G
Assignee: Uma Maheswara Rao G
When users try to connect to remote cluster from the cluster env where you
enabled ViewFSOverloadScheme, it expects to have at least one mount link make
fs init success.
Unfortunately you might not have configured any mount links with that remote
cluster in your current env. You would have configured only with your local
clusters mount points.
In this case fs init will fail with no mount points configured the mount table
if that remote cluster uri's authority.
One idea is that, when there are no mount links configured, we should just
consider that as default cluster, that can be achieved by considering it as
fallback option automatically.
