DRILL-7257: Set nullable var-width vector lastSet value Turns out this is due to a subtle issue with variable-width nullable vectors. Such vectors have a lastSet attribute in the Mutator class. When using "transfer pairs" to copy values, the code somehow decides to zero-fill from the lastSet value to the record count. The row set framework did not set this value, meaning that the RemovingRecordBatch zero-filled the dir0 column when it chose to use transfer pairs rather than copying values. The use of transfer pairs occurs when all rows in a batch pass the filter prior to the removing record batch. Modified the nullable vector writer to properly set the lastSet value at the end of each batch. Added a unit test to verify the value is set correctly. Includes a bit of code clean-up.
Apache Drill is a distributed MPP query layer that supports SQL and alternative query languages against NoSQL and Hadoop data storage systems. It was inspired in part by Google's Dremel.
Please read Environment.md for setting up and running Apache Drill. For complete developer documentation see DevDocs.md
