This patch creates a new function,\nProcessScratchBatch, which contains the inner loop of\nTransferScratchTuples, allowing us to cross-compile only this\nperformance critical part. It also uses CodegenEvalConjuncts to\nreplace the call to EvalConjuncts in ProcessScratchBatch with a\ncodegen'd version.\n\nAdditionally, it modifies the Codegen functions in\nhdfs-avro/text/sequence-scanner to take an output parameter for\nthe codegen'd function and return a Status in order to improve\nlogging around codegen failures.\n\nChange-Id: Ic327e437c7cd2b3f92cdb11c1e907bfee2d44ee8\nReviewed-on: http://gerrit.cloudera.org:8080/4093\nReviewed-by: Thomas Tauber-Marshall <tmarshall@cloudera.com>\nReviewed-by: Matthew Jacobs <mj@cloudera.com>\nTested-by: Internal Jenkins","distinct":true,"url":"https://api.github.com/repos/apache/incubator-impala/commits/9e438a08f1fa5761a88f0c9329bfedaeae3206d1"}]}
