[jira] [Created] (HADOOP-13738) DiskChecker should perform some
file IO
Arpit Agarwal created HADOOP-13738:
--------------------------------------
Summary: DiskChecker should perform some file IO
Key: HADOOP-13738
URL: https://issues.apache.org/jira/browse/HADOOP-13738
Project: Hadoop Common
Issue Type: Improvement
Reporter: Arpit Agarwal
Assignee: Arpit Agarwal
DiskChecker can fail to detect total disk/controller failures indefinitely. We have seen this in real clusters. DiskChecker performs simple permissions-based checks on directories which do not guarantee that any disk IO will be attempted.
A simple improvement is to write some data and flush it to the disk.
