- Verified signatures and digests- Spot checked CHANGES.txt files- Successfully 
performed a native build from source- Deployed to a single node cluster and ran 
sample jobs
We have been running with the fix for YARN-4354 on two of our clusters for some 
time with no issues, so I feel confident that prior blocker is now fixed.

 Subject: [VOTE] Release Apache Hadoop 2.7.2 RC1
   
Hi all,

I've created a release candidate RC1 for Apache Hadoop 2.7.2.

As discussed before, this is the next maintenance release to follow up 2.7.1.

The RC is available for validation at: 
http://people.apache.org/~vinodkv/hadoop-2.7.2-RC1/ 


The RC tag in git is: release-2.7.2-RC1

The maven artifacts are available via repository.apache.org 
 at 
https://repository.apache.org/content/repositories/orgapachehadoop-1026/ 


The release-notes are inside the tar-balls at location 
hadoop-common-project/hadoop-common/src/main/docs/releasenotes.html. I hosted 
this at http://people.apache.org/~vinodkv/hadoop-2.7.2-RC1/releasenotes.html 
for quick perusal.

As you may have noted,
 - The RC0 related voting thread got halted due to some critical issues. It 
took a while again for getting all those blockers out of the way. See the 
previous voting thread [3] for details.
 - Before RC0, an unusually long 2.6.3 release caused 2.7.2 to slip by quite a 
bit. This release's related discussion threads are linked below: [1] and [2].

Please try the release and vote; the vote will run for the usual 5 days.

Thanks,
Vinod

Re: [Important] Lots of 2.8.0 commits are in branch-2 only

2015-12-18 Thread Wangda Tan 
Update:

It seems "git log" diff compare has some bugs that cherry-picks cannot be
recognized properly sometimes.

Worked with Vinod to directly compare JIRA tickets and git log result. We
finally found 20 JIRAs (list below) which fix version is 2.8.0 and not in
branch-2.8. I've backported all of them to branch-2.8, run build and pushed
to branch-2.8.

> YARN-4416
> YARN-4225
> YARN-4293
> YARN-4440
> YARN-4418
> YARN-4309
> YARN-3946

Please check if any of your patches is in branch-2 only but fix version is
2.8.0.

Will update JIRAs as well.

Thanks,
Wangda

[jira] [Created] (HADOOP-12659) Incorrect usage of config parameters in token manager of KMS

2015-12-18 Thread Tianyin Xu (JIRA) 
Tianyin Xu created HADOOP-12659:
---

 Summary: Incorrect usage of config parameters in token manager of 
KMS
 Key: HADOOP-12659
 URL: https://issues.apache.org/jira/browse/HADOOP-12659
 Project: Hadoop Common
  Issue Type: Bug
  Components: security
Affects Versions: 2.6.2, 2.7.1
Reporter: Tianyin Xu


Hi, the usage of the following configs of Key Management Server (KMS) are 
problematic: 
{{hadoop.kms.authentication.delegation-token.renew-interval.sec}}
{{hadoop.kms.authentication.delegation-token.removal-scan-interval.sec}}

The name indicates that the units are {{sec}}, and the online doc shows that 
the default values are {{86400}} and {{3600}}, respectively.
https://hadoop.apache.org/docs/stable/hadoop-kms/index.html
which is also defined in
{code:title=DelegationTokenManager.java|borderStyle=solid}
 55   public static final String RENEW_INTERVAL = PREFIX + "renew-interval.sec";
 56   public static final long RENEW_INTERVAL_DEFAULT = 24 * 60 * 60;
 ...
 58   public static final String REMOVAL_SCAN_INTERVAL = PREFIX +
 59   "removal-scan-interval.sec";
 60   public static final long REMOVAL_SCAN_INTERVAL_DEFAULT = 60 * 60;
{code}

However, in {{DelegationTokenManager.java}} and 
{{ZKDelegationTokenSecretManager.java}}, these two parameters are used 
incorrectly.

1. *{{DelegationTokenManager.java}}*
{code}
 70   conf.getLong(RENEW_INTERVAL, RENEW_INTERVAL_DEFAULT) * 1000,
 71   conf.getLong(REMOVAL_SCAN_INTERVAL, 
 72   REMOVAL_SCAN_INTERVAL_DEFAULT * 1000));
{code}

Apparently, at Line 72, {{REMOVAL_SCAN_INTERVAL}} should be used in the same 
way as {{RENEW_INTERVAL}}, like
{code}
72c72
<   REMOVAL_SCAN_INTERVAL_DEFAULT * 1000));
---
>   REMOVAL_SCAN_INTERVAL_DEFAULT) * 1000);
{code}
Currently, the unit of 
{{hadoop.kms.authentication.delegation-token.removal-scan-interval.sec}} is not 
{{sec}} but {{millisec}}.

2. *{{ZKDelegationTokenSecretManager.java}}*
{code}
142 conf.getLong(DelegationTokenManager.RENEW_INTERVAL,
143 DelegationTokenManager.RENEW_INTERVAL_DEFAULT * 1000),
144 conf.getLong(DelegationTokenManager.REMOVAL_SCAN_INTERVAL,
145 DelegationTokenManager.REMOVAL_SCAN_INTERVAL_DEFAULT) * 1000);
{code}
 The situation is the opposite in this class that 
{{hadoop.kms.authentication.delegation-token.renew-interval.sec}} is wrong but 
the other is correct...
A patch should be like
{code}
143c143
< DelegationTokenManager.RENEW_INTERVAL_DEFAULT * 1000),
---
> DelegationTokenManager.RENEW_INTERVAL_DEFAULT) * 1000,
{code}

Thanks!
