Change subject: IMPALA-3629: Codegen TransferScratchTuples() in hdfs-parquet-scanner ...................................................................... IMPALA-3629: Codegen TransferScratchTuples() in hdfs-parquet-scanner We currently don't do any codegen in the hdfs-parquet scanner, which limits performance. This patch creates a new function, ProcessScratchBatch, which contains the inner loop of TransferScratchTuples, allowing us to cross-compile only this performance critical part. It also uses CodegenEvalConjuncts to replace the call to EvalConjuncts in ProcessScratchBatch with a codegen'd version. Additionally, it modifies the Codegen functions in hdfs-avro/text/sequence-scanner to take an output parameter for the codegen'd function and return a Status in order to improve logging around codegen failures.
