Patch Set 10: (1 comment) http://gerrit.cloudera.org:8080/#/c/1901/10/be/src/exec/topn-node.cc File be/src/exec/topn-node.cc: Line 79: sort_exec_exprs_.sort_tuple_slot_expr_ctxs(), NULL, &materialize_exprs_no_pool_fn)); > what's the problem with having just a single symbol? You mean a single symbol for the pool and no pool case? I wanted to remove the conditionals checking if pool is NULL, requiring two different codegen'd functions for the NULL and non-NULL cases. Then I need to know which function calls to replace with which codegen'd function, so I created two different symbols for the original functions too. Given how much confusion this has caused (there was a lot of discussion about this previously too), maybe I should have ReplaceCallSites() optionally take a vector<Type*> argument that is the signature to look for, in addition to the symbol.
