Aggarwal-Raghav · 2025-09-01T16:13:02Z

What changes were proposed in this pull request?

Although Hive has moved to Jline3, 2.x was also getting shipped in packaging.

Why are the changes needed?

To have single Jline jar. Check HIVE-29130 for more details

Does this PR introduce any user-facing change?

No

How was this patch tested?

On local setup

Aggarwal-Raghav · 2025-09-01T16:17:30Z

As Hadoop has jline 3.9.0**, in my setup** it was getting picked first compared to 3.25.0 from hive. Causing NoSuchMethodError org.jline.reader.EndOfFileException#getPartialLine() check here.

I would like the reviewer to confirm on this.

thanks @Aggarwal-Raghav for taking care of this, would you be so kind to add an enforcer item so ban this dependency even transitively in the future? that would be the perfect solution I believe

removing commons-logging as it was getting packaged in beeline tarball. Check HIVE-24691 and HIVE-20019

removed the enforcer pluging from standalone-metastore/metastore-common/pom.xml and standalone-metastore/metastore-server/pom.xml and moved to standalone-metastore/pom.xml i.e. a common place and updated it with the same list of banned dependency as in parent pom.xml

Aggarwal-Raghav · 2025-09-03T06:42:06Z

The unit test failures in this PR are relevant. The reason for this is that Pig version 0.16.0 uses jline 1.x. The jline dependency is being excluded from Pig due to an enforcer rule, which is causing failures specifically in the hcatalog/hcatalog-pig-adapter module.
I believe the current unit test scenario in the cluster/runtime environment might also be failing because we are not shipping jline 1.x. Assumption: This would only work if jline 2.x, which is being shipped without this PR, is backward compatible with version 1.x.

My recommendation for the next step is to remove the jline enforcer rule from the parent pom.xml, keeping the exclusions everywhere else except hcatalog/hcatalog-pig-adapter. Is that the approach acceptable? Still with this approach [2] i.e. pig working in cluster is unknown.

Hadoop's JLine 3.9.0 it was getting picked up first. So, we should make sure Hive Classpath is always before HADOOP jars.

I don't understand in that scope or for this problem why are we playing with Jline-2.x?

I am not very convinced on enforcing some places and not on some. We might not have a use case or expertise with Pig, so better not to touch it in that case. We had a thread around Pig to depreacate/remove some time back & we were shot down, so people tend to use it

Why not upgrade JLine in Hadoop?

it is what it is, thanks @Aggarwal-Raghav for checking, but before proceeding with this, can you please check if there is an include/exclude possibility in bannedDependencies to allow old jline transitively through pig only, does it make sense?

Aggarwal-Raghav · 2025-09-03T07:30:50Z

Thanks for the reply @ayushtkn.

I don't understand in that scope or for this problem why are we playing with Jline-2.x?

In hive packaging, both jline 2.11 and jline 3.25.0 are getting shipped. IMO, its wrong. The aim of this PR is to ship only jline3.x jar. If we are ok shipping both the version then I'll close this PR.

Why not upgrade JLine in Hadoop?

It's good to have same dependency version across components. In my setup, Jline 3.9.0 is getting picked up first which is causing NoSuchMethodError. -- I want to confirm if its due to my setup or not.

In conclusion,

if Hadoop Classpath first, then jline 3.9.0 is picked => hadoop has to upgrade jline to 3.25.0
if hive classpath is first, then we are all good.

In conclusion,
if Hadoop Classpath first, then jline 3.9.0 is picked => hadoop has to upgrade jline to 3.25.0
if hive classpath is first, then we are all good.

So, the solution is like in ideal setup Hive Classpath should be first. In that case we are sorted. Else for the problem that you reported. Hadoop needs to upgrade JLine, correct?

And this PR is solving a different problem as reported in the ticket, this won't solve the problem that you reported?

Aggarwal-Raghav · 2025-09-03T11:16:44Z

UT passed in local.

cd hcatalog/hcatalog-pig-adapter ; mvn clean test -Dtest=TestTextFileHCatLoader,TestRCFileHCatLoader,TestAvroHCatLoader,TestSequenceFileHCatLoader,TestParquetHCatLoader,TestOrcHCatLoader -Drat.skip

Pushed the changes. Will see CI output.

nit: please explain here with a brief comment why we still allow 1.0 to make it clear for the future if we can remove

abstractdog · 2025-09-03T12:37:29Z

thanks @Aggarwal-Raghav, I'm good now with the pom.xml changes, but haven't followed if you've reached consensus with @ayushtkn on the other aspect of this PR, please let me know guys

Aggarwal-Raghav · 2025-09-03T15:08:41Z

@ayushtkn, can you please take a look once!

Aggarwal-Raghav · 2025-09-11T17:24:27Z

gentle ping for review @ayushtkn !

ayushtkn · 2025-09-11T17:41:23Z

Stuck with some stuff. If @abstractdog is happy. I am happy. feel free to move ahead :-)

- jline2.x has been added to enforcer plugin - commons-logging direct dependency has been removed from standalone-metastore module - enforcer plugin in standalone-metastore is now same as of parent pom.xml
