--------------------------------------

             Summary: add isHealthy interface/test to filesystems for JT &c to use
                 Key: HADOOP-9547
                 URL: https://issues.apache.org/jira/browse/HADOOP-9547
             Project: Hadoop Common
          Issue Type: Improvement
    Affects Versions: 3.0.0, 1.3.0
            Reporter: Steve Loughran
            Priority: Minor


There are specific {{isHealthy()}} tests for HDFS; in {{DistributedFilesystem}} in branch-1;
{{HdfsUtils}} in trunk -tests used by layers above. 

All filesystems have the right to be unhealthy; we should make the probe something each FS
can implement, with a probe operation that can be called independent of the underlying FS.
