-------------------------------------------
Summary: Support auto-refresh of latest viewDFS mount configuration
Key: HDFS-17583
URL: https://issues.apache.org/jira/browse/HDFS-17583
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Palakur Eshwitha Sai
Assignee: Palakur Eshwitha Sai
Currently, the central mount table configuration feature for viewDFS loads the
latest mounts each time the viewDFS initialize function is called. But in the
case of use cases with hive, hive does the call to initialize the fs only for
the first time after HS2 restart. From then on, it fetches the filesystem/
resolved mount points from the cache.
This requires HS2 restart each time some data is moved to S3 or other hadoop
compatible file systems and a new mount-table.xml file is added to the viewDFS
central mount config directory, which is not ideal.
Should implement a way in which the mount table is auto loaded at specific
intervals/ each time the central mount-table directory is updated with a new
mount-table.xml file.
