Datanodes should shutdown when a critical volume fails
------------------------------------------------------
Key: HDFS-1848
URL: https://issues.apache.org/jira/browse/HDFS-1848
Project: Hadoop HDFS
Issue Type: Improvement
Components: data-node
Reporter: Eli Collins
Fix For: 0.23.0
A DN should shutdown when a critical volume (eg the volume that hosts the OS,
logs, pid, tmp dir etc.) fails. The admin should be able to specify which
volumes are critical, eg they might specify the volume that lives on the boot
disk. A failure in one of these volumes would not be subject to the threshold
(HDFS-1161) or result in host decommissioning (HDFS-1847) as the
decommissioning process would likely fail.
