I think kColumnNotFound is -1 Oops. Turns out that didn't cause any problems because of how we're using projection_vc_is_deleted_idx_, but good to fix regardless. http://gerrit.cloudera.org:8080/#/c/10990/5/src/kudu/tablet/memrowset.cc File src/kudu/tablet/memrowset.cc: http://gerrit.cloudera.org:8080/#/c/10990/5/src/kudu/tablet/memrowset.cc@404 PS5, Line 404: projection > if projection is a schema, could we just use find_column here?
