Steve Loughran commented on PARQUET-2158:
-----------------------------------------
build is broken by HADOOP-12436
{code}
Error: Failed to execute goal
org.apache.maven.plugins:maven-compiler-plugin:3.8.1:compile (default-compile)
on project parquet-thrift: Compilation failure
Error:
/home/runner/work/parquet-mr/parquet-mr/parquet-thrift/src/main/java/org/apache/parquet/thrift/projection/deprecated/PathGlobPattern.java:[55,49]
incompatible types: com.google.re2j.Pattern cannot be converted to
java.util.regex.Pattern
{code}
That was a change to a class believed to be private; clearly not.
> Upgrade Hadoop dependency to version 3.2.0
> ------------------------------------------
>
> Key: PARQUET-2158
> URL: https://issues.apache.org/jira/browse/PARQUET-2158
> Project: Parquet
> Issue Type: Improvement
> Components: parquet-mr
> Affects Versions: 1.13.0
> Reporter: Steve Loughran
> Priority: Major
>
> Parquet still builds against Hadoop 2.10. This is very out of date and does
> not work with java 11, let alone later releases.
> Upgrading the dependency to Hadoop 3.2.0 makes the release compatible with
> java 11, and lines up with active work on HADOOP-18287, _Provide a shim
> library for modern FS APIs_
> This will significantly speed up access to columnar data, especially in
> cloud stores.
