For those not well versed in sbt shading, the following would pin your project
at parquet-avro 1.8.1.
In your project/plugins.sbt:
{code}
addSbtPlugin("com.eed3si9n" % "sbt-assembly" % "0.14.5")
{code}
In your build.sbt:
{code}
libraryDependencies += ("org.apache.parquet" % "parquet-avro" %
"1.8.1").intransitive()
assemblyShadeRules in assembly := Seq(
ShadeRule.rename("org.apache.parquet.avro.**" -> "shade.parquet.avro.@1")
.inLibrary("org.apache.parquet" % "parquet-avro" % "1.8.1")
.inProject
)

This is caused by a bug in Parquet that has been fixed in 1.8.2, so you want the 1.8.2 version of parquet-hadoop, but the 1.8.1 version of parquet-avro. Alternatively, you can shade and relocate the version of Avro you want and use parquet-avro 1.8.2. That's what I'd recommend. > Roll back parquet-mr 1.8.2 to parquet-1.8.1 > --- > > Key: SPARK-20958 > URL: https://issues.apache.org/jira/browse/SPARK-20958 > Project: Spark > Issue Type: Bug > Components: SQL >Affects Versions: 2.2.0 >Reporter: Cheng Lian >Assignee: Cheng Lian > Labels: release-notes, release_notes, releasenotes > > We recently realized that parquet-mr 1.8.2 used by Spark 2.2.0-rc2 depends on > avro 1.8.1, which is incompatible with avro 1.7.6 used by parquet-mr 1.8.1 > and avro 1.7.7 used by spark-core 2.2.0-rc2. > Basically, Spark 2.2.0-rc2 introduced two incompatible versions of avro > (1.7.7 and 1.8.1).

some exceptions that I had. This will hopefully make search engines find this

I'm also reluctant to roll it back considering those fixes we wanted so badly... We decided to give this a try because, from the perspective of release management, we'd like to avoid cutting a release with known conflicting dependencies, even transitive ones. For a Spark 2.2 user, it's quite natural to choose parquet-avro 1.8.2, which is part of parquet-mr 1.8.2, which in turn, is a direct dependency of Spark 2.2.0. However, due to PARQUET-389, rolling back is already not an option. Two options I can see here are: # Release Spark 2.2.0 as is with a statement in the release notes saying that users should use parquet-avro 1.8.1 instead of 1.8.2 to avoid the Avro compatibility issue. # Wait for parquet-mr 1.8.3, which hopefully resolves this dependency issue (e.g., by reverting PARQUET-358). > Roll back parquet-mr 1.8.2 to parquet-1.8.1 > --- > > Key: SPARK-20958 > URL: https://issues.apache.org/jira/browse/SPARK-20958 > Project: Spark > Issue Type: Bug > Components: SQL >Affects Versions: 2.2.0 >Reporter: Cheng Lian >Assignee: Cheng Lian > > We recently realized that parquet-mr 1.8.2 used by Spark 2.2.0-rc2 depends on > avro 1.8.1, which is incompatible with avro 1.7.6 used by parquet-mr 1.8.1 > and avro 1.7.7 used by spark-core 2.2.0-rc2. > Basically, Spark 2.2.0-rc2 introduced two incompatible versions of avro > (1.7.7 and 1.8.1).

Ryan Blue commented on SPARK-20958:

I don't think it is a good idea to roll back. Spark doesn't depend on
parquet-avro, where the update to Avro 1.8.1 was made, except for tests where
it is fine. The backports for Spark in 1.8.2 are worth keeping since there are
reasonable work-arounds in user projects.
The problem that I've seen on the dev list is when users add parquet-avro to
their dependencies and the version gets managed to 1.8.2. That will require
Avro 1.8.1 because parquet-avro calls {{getSchema}} on avro-specific objects.
But there are a couple reasonable ways to deal with this:
1. Specify a dependency on parquet-avro 1.8.1 that still uses Avro 1.7.x.
Parquet is backward-compatible with older binaries, so parquet-avro 1.8.1 works
fine with parquet-hadoop 1.8.2. (This is the recommended work-around.)
2. Shade and relocate Avro 1.8.1 in application Jars, so that Spark can use
1.7.x and parquet-avro can use 1.8.1.
This was brought up on the dev list, but the user dismissed these work-arounds
without trying them.
Long-term, we can do a 1.8.3 release to solve this problem, though I think the
best solution there would be to stop using {{getSchema}} instead of downgrading
the dependency.

Tried to roll back parquet-mr back to 1.8.1 but it doesn't work well because this brings back [PARQUET-389|https://issues.apache.org/jira/browse/PARQUET-389] and breaks some test cases involving schema evolution. It would be nice if we can have a parquet-mr 1.8.3 or 1.8.2.1 release that has [PR #318|https://github.com/apache/parquet-mr/pull/318] reverted from 1.8.2? I think cherry-picking that PR is also problematic for parquet-mr because it introduces a backward-incompatible dependency change in a maintenance release. > Roll back parquet-mr 1.8.2 to parquet-1.8.1 > --- > > Key: SPARK-20958 > URL: https://issues.apache.org/jira/browse/SPARK-20958 > Project: Spark > Issue Type: Bug > Components: SQL >Affects Versions: 2.2.0 >Reporter: Cheng Lian >Assignee: Cheng Lian > > We recently realized that parquet-mr 1.8.2 used by Spark 2.2.0-rc2 depends on > avro 1.8.1, which is incompatible with avro 1.7.6 used by parquet-mr 1.8.1 > and avro 1.7.7 used by spark-core 2.2.0-rc2. > Basically, Spark 2.2.0-rc2 introduced two incompatible versions of avro > (1.7.7 and 1.8.1).
