If there's a char field in the tuple. I think this is a step back in terms of error messages, so I added back an explicit check for CHAR fields in the intermediate tuple. I actually noticed there are a couple of places in the codebase that don't check for a null result from this function, so I fixed those. http://gerrit.cloudera.org:8080/#/c/4655/12/be/src/exprs/aggregate-functions-ir.cc File be/src/exprs/aggregate-functions-ir.cc: PS12, Line 630: ; > remove Done http://gerrit.cloudera.org:8080/#/c/4655/12/be/src/runtime/descriptors.h File be/src/runtime/descriptors.h: PS12, Line 143: the > "a boolean value represented ..." ? like above comment.
