-----------------------------------
Summary: Support viewfs in Sentry Namenode plugin
Key: SENTRY-1627
URL: https://issues.apache.org/jira/browse/SENTRY-1627
Project: Sentry
Issue Type: New Feature
Components: Hdfs Plugin, Hive Plugin, Sentry
Affects Versions: 1.5.1
Reporter: Qianbo Huai
Fix For: 1.5.1
The View File System (ViewFs) provides a way to manage multiple Hadoop file
system namespaces (or namespace volumes). It is particularly useful for
clusters having multiple namenodes, and hence multiple namespaces, in HDFS
Federation. ViewFs is analogous to client side mount tables in some Unix/Linux
systems.
In a ViewFs deployment, Sentry MetastorePlugin sees viewfs schemed paths but
drops them in PathsUpdate.parsePath as it hardcodes the support for only hdfs
schemed path.
If paths updates are sent to Sentry Namenode plugin, the viewfs paths need to
be converted to per-namenode (HDFS cluster) paths.
