we are doing Java 8 alongside Java 7, but nobody is worrying about the java 8 
build failing. (not enough people are worrying about java 7, either)

switching to Java 8 only (with that source flag), is simply a matter of 
stopping the java 7 build and having everyone agree to care about jenkins trunk 
builds.

+1, though that was very much a patch backlog day.

I want us all to care more about failing jenkins builds and react fast to 
failures

[jira] [Created] (HADOOP-12414) MapFile.Reader get method does not return the first record in case of non unique keys

[mayur (JIRA)]

 Summary: MapFile.Reader get method does not return the first 
record in case of non unique keys
 Key: HADOOP-12414
 URL: https://issues.apache.org/jira/browse/HADOOP-12414
 Project: Hadoop Common
  Issue Type: Bug
Reporter: mayur


If the map file has multiple records with the same keys and MapFile.Reader is 
used to reset to a specific key using the MapFile.Reader.get(key,val) then is 
does not always seeks to the first record of the given key.

Re: [DISCUSS] fixing jenkins; policing the build

[Chris Nauroth]

It would be great if we could get to a point where a failure in the
nightly builds automatically creates a blocker JIRA against the branch's
corresponding version.  Our tests are nowhere near stable enough for that
to be realistic right now, so it would have to be a long-term improvement.
 We'd have to invest effort into stabilizing the tests first.

As a side effect, stabilizing the tests would make it feasible to enable
parallel execution of tests for faster pre-commit.  This is tracked in
HADOOP-11984.  I stabilized a few of the tests while working on that, but
I had to put the effort on hold.

[jira] [Created] (HADOOP-12415) Hadoop build is broken because of missed compile-time dependency

[Konstantin Boudnik (JIRA)]

Konstantin Boudnik created HADOOP-12415:

 Summary: Hadoop build is broken because of missed compile-time 
dependency
 Key: HADOOP-12415
 URL: https://issues.apache.org/jira/browse/HADOOP-12415
 Project: Hadoop Common
  Issue Type: Bug
  Components: nfs
Affects Versions: 2.7.1
Reporter: Konstantin Boudnik


As discovered in BIGTOP-2049 {{hadoop-nfs}} module compilation is broken. Looks 
like that HADOOP-11489 is the root-cause of it.

> Provide an NFS gateway option to get groups from local name service for easy 
> deployment in cloud
> 
>
> Key: HADOOP-10761
> URL: https://issues.apache.org/jira/browse/HADOOP-10761
> Project: Hadoop Common
>  Issue Type: New Feature
>  Components: nfs
>Affects Versions: 3.0.0
>Reporter: Brandon Li
> Attachments: RpcProgramNfs3.java, SysSecurityHandler.java, patch.txt
>
>
> In cloud deployment, client machines and Hadoop Cluster are sometimes in 
> different DMZ and LDAP in some other. Integration client machines with LDAP 
> might require lot of firewall tickets, which can be a pain especially when 
> users keep on adding new client machines.
> When the client is not integrated with LDAP for the group mapping, NFS should 
> not use the group list in the request. Instead, NFS gateway can get the group 
> list from local name service.
> This JIRA is to track the effort to provide a configuration option to get 
> list of GID from LDAP/OS for making the deployment at Cloud easier. Also this 
> can remove the limitation of 15 GID in the NFS request.
