Andrew Wang commented on HADOOP-9985:
-------------------------------------
Hey Lohit,
Why not use the default FS config parameter (fs.default.name) instead of using
fully-qualified URLs? Then you just need to change the client config when
switching clusters.
> HDFS Compatible ViewFileSystem
> ------------------------------
>
> Key: HADOOP-9985
> URL: https://issues.apache.org/jira/browse/HADOOP-9985
> Project: Hadoop Common
> Issue Type: Bug
> Reporter: Lohit Vijayarenu
> Fix For: 2.0.6-alpha
>
>
> There are multiple scripts and projects like pig, hive, elephantbird refer to
> HDFS URI as hdfs://namenodehostport/ or hdfs:/// . In federated namespace
> this causes problem because supported scheme for federation is viewfs:// . We
> will have to force all users to change their scripts/programs to be able to
> access federated cluster.
> It would be great if thee was a way to map viewfs scheme to hdfs scheme
> without exposing it to users. Opening this JIRA to get inputs from people who
> have thought about this in their clusters.
> In our clusters we ended up created another class
> HDFSCompatibleViewFileSystem which hijacks both hdfs.fs.impl and
> viewfs.fs.impl and passes down filesystem calls to ViewFileSystem. Is there
> any suggested approach other than this?
