Subject [jira] [Created] (HDFS-15112) RBF: do not return FileNotFoundException when a subcluster is unavailable
Date Sat, 11 Jan 2020 01:46:00 GMT
Íñigo Goiri created HDFS-15112:
----------------------------------

             Summary: RBF: do not return FileNotFoundException when a subcluster is unavailable

                 Key: HDFS-15112
                 URL: https://issues.apache.org/jira/browse/HDFS-15112
             Project: Hadoop HDFS
          Issue Type: Improvement
            Reporter: Íñigo Goiri


If we have a mount point using HASH_ALL across two subclusters and one of them is down, we
may return FileNotFoundException while the file is just in the unavailable subcluster.
We should not return FileNotFoundException but something that shows that the subcluster is
unavailable.
