-----------------------------------------
Summary: 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
Reporter: Virajith Jalaparti
Assignee: Virajith Jalaparti
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.
