Hi, The last commit in parquet-mr master (c6764c4a0848abf1d581e22df8b33e28ee9f2ced) does not build with jdk7 only with jdk8. We did not catch the issue because either Travis and me use jdk8 to build parquet-mr. (The source level in the pom.xml is set to 1.7 so both jdk7 and jdk8 should be able to build it but jdk7 fails with “invalid inferred types for T; inferred type does not conform to declared bound(s)”.)
I think we have 2 options: 1. Fix the code so it compiles with both jdk7 and jdk8. In this case Travis should be updated to check both otherwise we might have similar issues in the future. 2. Bump up source/target levels to java8. What do you think? Thanks, Gabor
