Paul Rogers resolved DRILL-7311. -------------------------------- Resolution: Duplicate > Partial fixes for empty batch bugs > ---------------------------------- > > Key: DRILL-7311 > URL: https://issues.apache.org/jira/browse/DRILL-7311 > Project: Apache Drill > Issue Type: Bug > Affects Versions: 1.16.0 > Reporter: Paul Rogers > Assignee: Paul Rogers > Priority: Major > Fix For: 1.18.0 > > > DRILL-7305 explains that multiple operators have serious bugs when presented > with empty batches. DRILL-7306 explains that the EVF (AKA "new scan > framework") was originally coded to emit an empty "fast schema" batch, but > that the feature was disabled because of the many empty-batch operator > failures. > This ticket covers a set of partial fixes for empty-batch issues. This is the > result of work done to get the converted JSON reader to work with a "fast > schema." The JSON work, in the end, revealed that Drill has too many bugs to > enable fast schema, and so the DRILL-7306 was implemented instead. -- This message was sent by Atlassian Jira (v8.3.4#803005)
