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

             Summary: SnapshotAccessControlException does not return valid exit codes
                 Key: HDFS-4736
                 URL: https://issues.apache.org/jira/browse/HDFS-4736
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Ramya Sunil
             Fix For: Snapshot (HDFS-2802)


When some dfs operations fail due to SnapshotAccessControlException, valid exit codes are not returned.

E.g:
-bash-4.1$  hadoop dfs -chmod -R 755 /user/foo/hdfs-snapshots/test0/.snapshot/s0
chmod: changing permissions of 'hdfs://<namenode>:8020/user/foo/hdfs-snapshots/test0/.snapshot/s0':org.apache.hadoop.hdfs.server.namenode.snapshot.SnapshotAccessControlException: Modification on read-only snapshot is disallowed

-bash-4.1$ echo $?
0

-bash-4.1$  hadoop dfs -chown -R hdfs:users /user/foo/hdfs-snapshots/test0/.snapshot/s0
chown: changing ownership of 'hdfs://<namenode>:8020/user/foo/hdfs-snapshots/test0/.snapshot/s0':org.apache.hadoop.hdfs.server.namenode.snapshot.SnapshotAccessControlException: Modification on read-only snapshot is disallowed

-bash-4.1$ echo $?
0
