Ramya Sunil created HDFS-4736:
---------------------------------
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
