I've just reverted both branch-2 and trunk, while the dist tarball is being 
built correctly, as Andrew pointed out site is not working, we have to fix that.

Re: HADOOP-8887 port to branch-2

[Andrew Purtell]

The build would fail in the "site" phase for me for some reason because of
a missing dependency management section. Adding dev-support as parent to
the new module fixed that.

Resolution: Fixed

Committed to branch-2 after tweaking POM versions, did a full build and 
verified all generated JARs are the correct version. Apologies for the noise.

Thanks Suresh, my bad, missed to tweak the POM versions when merging, I'll do 
it again (this time properly). Nicholas, as Colin indicated, javadoc warnings 
are taken care by the patch, just it does not show until the patch is committed 
(one of these days I'll try to tweak test-patch to do what we do in Oozie, we 
run javadoc twice, once without the patch and once with the patch, and we 
compare the warning numbers, less or equal good).

RE: Questions and possible improvements for LdapGroupsMapping

JIRA is opened for this:

Subject: RE: Questions and possible improvements for LdapGroupsMapping

Just got reply from user mailing list from Natty, as follows.
And I'd like to discuss further here since it's more appropriate.

Hi Natty,

1. It's great idea that we just write a customized group mapping service to 
handle different mapping for AD user and service principal; 2. OK, I'd like to 
improve it to support multiple ADs; 3. Great to know it. I will try the group 
mapping with OpenLDAP making use of the current configuration properties.

And further, to support to do different mapping for different user/principal, 
and support multiple ADs, we also need extra properties to configure what kind 
of user/principal (regarding domain/realm is an option) should use which group 
mapping mechanism.

To improve such things, I'm going to fire a JIRA for these. It would be great 
if you could continue to  comment on it. 

Thanks & regards,
Kai

Hi Kai,

1. To the best of my knowledge, you can only use one group mapping service at a 
time. In order to do what you're suggesting, you'd have to write a customized 
group mapping service.

2. Currently multiple ADs are not supported, but it's certainly an improvement 
that could be made.

3. The LdapGroupsMapping already supports OpenLDAP. It's pretty heavily 
configurable for the purpose of supporting multiple types of LDAP 
implementations. The defaults just happen to be geared towards Active Directory.

Thanks,
Natty

Subject: Questions and possible improvements for LdapGroupsMapping

Hi All,

Regarding LdapGroupsMapping, I have following questions:


1.   Is it possible to use ShellBasedUnixGroupsMapping for Hadoop service 
principals/users, and LdapGroupsMapping for end user accounts?
In our  environment, normal end users (along with their groups info) for Hadoop 
cluster are from AD, and for them we prefer to use the ldap mapping; but for 
hdfs/mapred service principals, the default shell based one is enough, and we 
don't want to create the user/group entries in AD just for that.
Seems in current implementation, only one user group mapping provider can be 
configured.


2.   Can we support multiple ADs? Hadoop users might come from more than 
ONE AD in big org.


3.   Is there any technical  issue not to support LDAPs like OpenLDAP? In 
my understanding, one possible difficulity might be that it's not easy to 
extract common
group lookup mechanism with common filters/configurations both applied for AD 
and OpenLDAP like, right?

I'm wondering if these are just limits for current implementation, and if so if 
we need to improve that. Might the community has already been going for that?

[jira] [Created] (HADOOP-8943) Enable to support multiple ADs and different group mapping for different user

[Kai Zheng (JIRA)]

Kai Zheng created HADOOP-8943:
-

 Summary: Enable to support multiple ADs and different group 
mapping for different user
 Key: HADOOP-8943
 URL: https://issues.apache.org/jira/browse/HADOOP-8943
 Project: Hadoop Common
  Issue Type: Improvement
  Components: security
Reporter: Kai Zheng
 Fix For: 2.0.3-alpha


Discussed with Natty about LdapGroupMapping, we need to improve it so that:
1. It's possible to do different group mapping for different users/principals. 
For example, AD user should go to LdapGroupMapping service for group, but  
service principals such as hdfs, mapred can still use the default one 
ShellBasedUnixGroupsMapping; 

2. Multiple ADs can be supported to do LdapGroupMapping;

3. It's possible to configure what kind of users/principals (regarding 
domain/realm is an option) should use which group mapping service/mechanism.

RE: Questions and possible improvements for LdapGroupsMapping

[Zheng, Kai]

Just got reply from user mailing list from Natty, as follows.
And I'd like to discuss further here since it's more appropriate.

Hi Natty,

1. It's great idea that we just write a customized group mapping service to 
handle different mapping for AD user and service principal;
2. OK, I'd like to improve it to support multiple ADs;
3. Great to know it. I will try the group mapping with OpenLDAP making use of 
the current configuration properties.

And further, to support to do different mapping for different user/principal, 
and support multiple ADs, we also need extra properties to 
configure what kind of user/principal (regarding domain/realm is an option) 
should use which group mapping mechanism.

To improve such things, I'm going to fire a JIRA for these. It would be great 
if you could continue to  comment on it. 

Thanks & regards,
Kai

Subject: Re: Secure hadoop and group permission on HDFS

Hi Kai,

1. To the best of my knowledge, you can only use one group mapping service at a 
time. In order to do what you're suggesting, you'd have to write a customized 
group mapping service.

2. Currently multiple ADs are not supported, but it's certainly an improvement 
that could be made.

3. The LdapGroupsMapping already supports OpenLDAP. It's pretty heavily 
configurable for the purpose of supporting multiple types of LDAP 
implementations. The defaults just happen to be geared towards Active Directory.

Thanks,
Natty

Subject: Questions and possible improvements for LdapGroupsMapping

Hi All,

Regarding LdapGroupsMapping, I have following questions:


1.   Is it possible to use ShellBasedUnixGroupsMapping for Hadoop service 
principals/users, and LdapGroupsMapping for end user accounts?
In our  environment, normal end users (along with their groups info) for Hadoop 
cluster are from AD, and for them we prefer to use the ldap mapping; but for 
hdfs/mapred service principals, the default shell based one is enough, and we 
don't want to create the user/group entries in AD just for that.
Seems in current implementation, only one user group mapping provider can be 
configured.


2.   Can we support multiple ADs? Hadoop users might come from more than 
ONE AD in big org.


3.   Is there any technical  issue not to support LDAPs like OpenLDAP? In 
my understanding, one possible difficulity might be that it's not easy to 
extract common
group lookup mechanism with common filters/configurations both applied for AD 
and OpenLDAP like, right?

I'm wondering if these are just limits for current implementation, and if so if 
we need to improve that. Might the community has already been going for that?

Re: HADOOP-8887 port to branch-2

[Colin McCabe]

Hmm.  It did build for me (in the sense of completing successfully, etc).

You've definitely found an issue, though.  The version should be
2.0.3-SNAPSHOT for those projects, not 3.0.0-SNAPSHOT.

Do you want to file a JIRA and post this patch, or should I?

cheers.
Colin

[jira] [Created] (HADOOP-8942) Thundering herd of RPCs with large responses leads to OOM

[Jason Lowe (JIRA)]

Jason Lowe created HADOOP-8942:
--

 Summary: Thundering herd of RPCs with large responses leads to OOM
 Key: HADOOP-8942
 URL: https://issues.apache.org/jira/browse/HADOOP-8942
 Project: Hadoop Common
  Issue Type: Bug
  Components: ipc
Affects Versions: 0.23.3
Reporter: Jason Lowe


When a large number of clients are all making calls with large amounts of 
response data then the IPC server can exhaust memory.  See MAPREDUCE-4730 for 
an example of this.

There does not appear to be any flow control between the server's handler 
threads and the responder thread.  If a handler thread cannot write out all of 
the response data without blocking, it queues up the remainder for the 
responder thread and goes back to the next call in the call queue.  If there 
are enough clients, this can cause the handler threads to overwhelm the heap by 
queueing response data faster than it can be processed.

Mailing list admin?

[Harsh J]

Hey project devs,

Can someone let me know who the MLs admin is? INFRA suggested that
instead of going to them, I could reach out to the admin group local
to the project itself (I didn't know we had admins locally).

P.s. Happy to volunteer to administrate as well.

Please ping me directly,
Thanks,
Harsh J
