chmod does not return error exit codes for some exceptions

Key: HADOOP-9502
URL: https://issues.apache.org/jira/browse/HADOOP-9502
Project: Hadoop Common
Issue Type: Bug
Components: fs
Reporter: Ramya Sunil
Assignee: Tsz Wo (Nicholas), SZE
Priority: Minor
Fix For: 1.2.0
Attachments: c9502_20130424.patch
When some dfs operations fail due to SnapshotAccessControlException, valid
exit codes are not returned.
E.g:
{noformat}
-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
{noformat}
Similar problems exist for some other exceptions such as SafeModeException.

[jira] [Created] (HADOOP-9503) Allow a configurable sleep between IPC client connect timeouts
Varun Sharma created HADOOP-9503: Summary: Allow a configurable sleep between IPC client connect timeouts Key: HADOOP-9503 URL: https://issues.apache.org/jira/browse/HADOOP-9503 Project: Hadoop Common Issue Type: Improvement Components: ipc Reporter: Varun Sharma Priority: Minor HADOOP 9106 introduced a configurable retry timeout when there are socket timeouts errors. Since the IPC client is used by a wide variety of applications including realtime/online ones (like hbase + hdfs), we sometimes need fast fail timeouts which are 3 seconds. Achieving such a timeout for connect is very difficult with a 1 second sleep in b/w retries. It would be good to have a configurable parameter to reduce this sleep. -- This message is automatically generated by JIRA.

Re: [DISCUSS] Getting to Hadoop 2.X beta
To add to it, here's what have been experiences as a disconnect during the release cycle of 2.0.4-alpha using BigTop 0.6.6 as the integration platform and management stack of choice: 1. Need for improved feedback from the downstream projects 2. Need for improved feedback from the DevOps Which boils down to getting sufficient buy-in from downstreams and devops communities that they are now willing to consider branch-2 as being landing spot for their Hadoop 2.X needs. I belive the recent effort around 2.0.4-alpha and BigTop 0.6.0 might be sufficient to convince both communities to: 1. migrate their Hadoop 2.X profiles to at least 2.0.4-alpha 2. start to run integration tests against Hadoop 2.X profile 3. start to publish Maven artifacts 4. in general agree to treat Hadoop 2.X issues with at least the same priority as the issues in default profiles are treated (which are mostly Hadoop 1.X profiles). that would be a good start. BigTop can certainly help with a lot of techicalities and moving parts of the process. That would require tighter coordination between releases, of course. The question I don't have an answer for is how to engage DevOps community. Thoughts?
