I know Avro is the unwanted child of the Drill world. (I know others have tried to mature the Avro support and that has been something that still is in a "experiemental" state.
That said, isn't it time for us to clean it up? I am sure I there are some open JIRAs out there, (last Doc update on the Avro Page, Nov 21, 2016) points to this https://issues.apache.org/jira/browse/DRILL/component/12328941/?selectedTab=com.atlassian.jira.jira-projects-plugin:component-summary-panel And I just ran into a issue... I am going to run it by here to see if it's JIRA worthy or known: I have two directories, one json (brodns) and one avro (brodnsavro) The both have subdirectories that are YYYY-MM-DD dates. Where I run select dir0, count(*) from `brodns` group by dir0 - This works great! when I run select dir0, count(*) from `brodnsavro` group by dir0 - I get: VALIDATION ERROR: From line 1, column 58 to line 1, column 61: Column 'dir0' not found in any table If I run select count(*) from `brodnsavro/2017-08-17` this works if I run select count(*) from `brodnsavro` this also works But dir0 doesn't appear to be applied to Avro. I really feel this should be consistent (in addition to fixing the other issues in Avro) and lets make Avro o a first class citizen of the Drill world. (If folks are interested, I'd be happy to discuss my use case, it involves applying a schema to json records on kafka/maprstreams in streamsets, and then outputting to avro files... from there I hope to convert to parquet, but don't want to use mapreduce, hence drill! )
