[SPARK-19970][SQL] Table owner should be USER instead of PRINCIPAL in kerberized clusters by dongjoon-hyun · Pull Request #17311 · apache/spark

dongjoon-hyun · 2017-03-16T09:19:22Z

What changes were proposed in this pull request?

In the kerberized hadoop cluster, when Spark creates tables, the owner of tables are filled with PRINCIPAL strings instead of USER names. This is inconsistent with Hive and causes problems when using ROLE in Hive. We had better to fix this.

BEFORE

scala> sql("create table t(a int)").show
scala> sql("desc formatted t").show(false)
...
|Owner:|spark@EXAMPLE.COM||

AFTER

scala> sql("create table t(a int)").show
scala> sql("desc formatted t").show(false)
...
|Owner:|spark ||

How was this patch tested?

Manually do create table and desc formatted because this happens in Kerberized clusters.

 }
 hiveTable.setPartCols(partCols.asJava)
- conf.foreach(c => hiveTable.setOwner(c.getUser))
+ conf.foreach(c => hiveTable.setOwner(SessionState.getUserFromAuthenticator()))


getUserFromAuthenticator was added 0.13.

 }
 hiveTable.setPartCols(partCols.asJava)
- conf.foreach(c => hiveTable.setOwner(c.getUser))
+ conf.foreach(c => hiveTable.setOwner(SessionState.get().getAuthenticator().getUserName()))


We cannot use the following since it was introduced in 0.13.
conf.foreach(c => hiveTable.setOwner(SessionState.getUserFromAuthenticator()))

Since you're touching this, could you make it follow the usual style?
.foreach { c => ... }

Thank you for review, @vanzin !
Which object do you mean for .foreach here?
For conf, we already use that.
For SessionState.get(), it's not Option.

There's only one foreach call and it's using a different style than the rest of the code.

Oh, I see. It's about removing .foreach.

No, it's about style. Parentheses v. braces.

Ah. Sorry again.

 }
 hiveTable.setPartCols(partCols.asJava)
- conf.foreach(c => hiveTable.setOwner(c.getUser))
+ conf.foreach { _ => hiveTable.setOwner(SessionState.get().getAuthenticator().getUserName()) }


Oh, I think we can remove conf here.

Ah, yes, you're not using it anymore. So away it goes.

@vanzin . Some test cases seems to related with conf is None, it causes failures. In this PR, I'll focus on putting the correct name only with the exactly same situations of the previous existing logic.

I think we should pass the user name.

Hi, @vanzin and @srowen .
Could you review this PR (again) when you have sometime?
I feel guilty because this PR need to be verified by manually on kerberized clusters.

Shouldn't you be using the state field in the class instead of SessionState.get()? Maybe that will allow you to get rid of the foreach.

state is in class HiveClientImpl, but this function is in object HiveClientImpl.

Ahh. Now it makes sense why conf would be None.

vanzin · 2017-03-20T17:06:54Z

LGTM, merging to master / 2.1.

dongjoon-hyun · 2017-03-20T17:08:03Z

Thank you so much, @vanzin !

Couldn't merge to 2.1.

dongjoon-hyun · 2017-03-20T17:09:58Z

Oh, I'll make a backport then.
