Patch Set 2: (3 comments) http://gerrit.cloudera.org:8080/#/c/5840/2/be/src/exec/kudu-scanner.cc File be/src/exec/kudu-scanner.cc: Line 149: if (slot->type().type != KuduColTypeToPrimitiveType(col.type())) { This doesn't address the case where you removed a column and then added a new one with the same type but with other attributes changed, eg. name and nullability. Do we keep our column names consistent with the column names in Kudu? If so, maybe we should log an error in that case, though probably not fail the query. http://gerrit.cloudera.org:8080/#/c/5840/2/common/thrift/generate_error_codes.py File common/thrift/generate_error_codes.py: PS2, Line 317: KUDU_COL_MISMATCH > nit: maybe call this 'KUDU_NUM_COLS_MISMATCH', else it sounds like it could Maybe also explicitly mention refreshing here, as above. http://gerrit.cloudera.org:8080/#/c/5840/2/tests/query_test/test_kudu.py File tests/query_test/test_kudu.py: Line 148: nit: extra line -- To view, visit http://gerrit.cloudera.org:8080/5840 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: I6d43f5bb9811e728ad592933066d006c8fb4553a Gerrit-PatchSet: 2 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Matthew Jacobs <m...@cloudera.com> Gerrit-Reviewer: Dan Hecht <dhe...@cloudera.com> Gerrit-Reviewer: Matthew Jacobs <m...@cloudera.com> Gerrit-Reviewer: Sailesh Mukil <sail...@cloudera.com> Gerrit-Reviewer: Thomas Tauber-Marshall <tmarsh...@cloudera.com> Gerrit-HasComments: Yes
