Subject [jira] [Updated] (HDFS-12730) Verify open files captured in the snapshots across config disable and enable
Date Fri, 27 Oct 2017 01:26:00 GMT

     [ https://issues.apache.org/jira/browse/HDFS-12730?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Manoj Govindassamy updated HDFS-12730:
--------------------------------------
    Description: 
Open files captured in the snapshots have their meta data preserved based on the config 
_dfs.namenode.snapshot.capture.openfiles_ (refer HDFS-11402). During the upgrade scenario
or when the NameNode gets restarted with config turned on or off,  the attributes of the open
files captured in the snapshots are influenced accordingly. Better to have a test case to
verify open file attributes across config turn on and off, and the current expected behavior
with HDFS-11402 so as to catch any regressions in the future.
