I’m trying to use the parquet-arrow library, which has just been updated to use Arrow 0.8.0 but unfortunately I am still running into this issue:
java.lang.ClassNotFoundException: org.apache.arrow.vector.types.pojo.ArrowType$Struct_ The class in the arrow jar is actually `Struct` not `Struct_`. This is due to Arrow using JDK 7 and Parquet using JDK 8. I have confirmed this on my forks and have submitted a PR to upgrade Arrow to JDK 1.8 but the CI tests are running against both JDK 7 and 8 and obviously the JDK 7 tests are failing. Is there any reason for maintaining JDK 7 compatibility? JDK 7 end of life was 3 years ago. Thanks, Andy.
