Uma Maheswara Rao G updated HDFS-15436:
---------------------------------------
Fix Version/s: 3.4.0
> Default mount table name used by ViewFileSystem should be configurable
> ----------------------------------------------------------------------
>
> 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
> Fix For: 3.4.0
>
>
> 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.
