@emkornfield @liyafan82 @kiszk Could you please help me review this PR? Thanks a lot. This is basically a fix for Dataset Java API to make it be able to scan within empty projector. The test cases is here https://github.com/apache/arrow/pull/10652/files#diff-8b46992e017975d0c5c66fc6d8c66a3e4b069e0caa0fad2cad52c7fb298f31b4R131-R174 Previous in Java we had null and empty projector indicating for "no projection" (all columns will be scanned out). This is to keep up with newest C++ code that empty projection means "scan for zero columns", only null projection is for "no projection" -- This is an automated message from the Apache Git Service.
