Hi all, I'm excited that we can support reading ORC complex types (IMPALA-6503) now!
I just finish the patch. As a community developer, I can't discuss with you Cloudera folks in real. It may be hard to make codes clear via comments for a big patch, so I wrote a doc about the implementation: https://docs.google.com/document/d/10Gzcge57VUOQ0ZQWfWiIW9cUix8_FumMewl0Gja3ZA4 (I may need to add more details, please let me know) Patch link: https://gerrit.cloudera.org/#/c/12168/ Have passed pre-review-test: https://jenkins.impala.io/job/pre-review-test/269/ Hopes you can take some time to review it. Thanks! Quanlong
