Sean Owen commented on SPARK-3794:
----------------------------------
The real problem here is that commons-io is not a dependency of Spark, and
should not be, but it began to be used a few days ago in commit
https://github.com/apache/spark/commit/cf1d32e3e1071829b152d4b597bf0a0d7a5629a2
for SPARK-1860. So it is accidentally depending on the version of Commons IO
brought in by third party dependencies.
I will propose a PR that removes this usage in favor of Guava or Java APIs.
> Building spark core fails with specific hadoop version

> Key: SPARK-3794
> URL: https://issues.apache.org/jira/browse/SPARK-3794
> Project: Spark
> Issue Type: Bug
> Components: Spark Core
> Affects Versions: 1.2.0
> Environment: Mac OS X 10.9.5
> Reporter: cocoatomo
> Labels: spark
>
> At the commit cf1d32e3e1071829b152d4b597bf0a0d7a5629a2, building spark core
> result in compilation error when we specify some hadoop versions.
> To reproduce this issue, we should execute following command with
> <hadoop.version>=1.1.0, 1.1.1, 1.1.2, 1.2.0, 1.2.1, or 2.2.0.
> {noformat}
> $ cd ./core
> $ mvn -Dhadoop.version=<hadoop.version> -DskipTests clean compile
> ...
> [ERROR]
> /Users/tomohiko/MyRepos/Scala/spark/core/src/main/scala/org/apache/spark/util/Utils.scala:720:
> value listFilesAndDirs is not a member of object
> org.apache.commons.io.FileUtils
> [ERROR] val files = FileUtils.listFilesAndDirs(dir,
> TrueFileFilter.TRUE, TrueFileFilter.TRUE)
> [ERROR] ^
> {noformat}
> Because that compilation uses commons-io version 2.1 and
> FileUtils#listFilesAndDirs method was added at commons-io version 2.2, this
> compilation always fails.
> FileUtils#listFilesAndDirs →
> http://commons.apache.org/proper/commons-io/apidocs/org/apache/commons/io/FileUtils.html#listFilesAndDirs%28java.io.File,%20org.apache.commons.io.filefilter.IOFileFilter,%20org.apache.commons.io.filefilter.IOFileFilter%29
> Because a hadoop-client in those problematic version depends on commons-io
> 2.1 not 2.4, we should have assumption that commons-io is version 2.1.
