Work Description: dmvk commented on issue #8923: [BEAM-7613]
HadoopFileSystem can work with more than one cluster.
URL: https://github.com/apache/beam/pull/8923#issuecomment-519549704
I've changed HadoopFileSystemRegistrar to work as follows:
- Resolve scheme from fs.defaultFS (compatible with original implementation)
- In case dfs.nameservices are configured, we imply HA hadoop cluster and
also register hdfs and webhdfs schemes
This should be backward compatible and also support multiple clusters. We
leave other settings up to the user to validate.
WDYT?

> _HadoopFileSystem_ creates underlying _FileSystem_ (one from
> org.apache.hadoop) instance during it's construction. Single _FileSystem_
> instance is tied to a particular cluster (scheme + authority pair). In case
> we want to talk to another cluster, this fail due to _FileSystem#checkPath_.
>
> This can be fixed by using _FileSystem#get(java.net.URI,
> org.apache.hadoop.conf.Configuration)_ instead of
> _FileSystem#newInstance(org.apache.hadoop.conf.Configuration)_{{}}
