Patch Set 5: (1 comment) http://gerrit.cloudera.org:8080/#/c/6527/5/be/src/exec/kudu-scan-node.cc File be/src/exec/kudu-scan-node.cc: Line 179: if (materialized_row_batches_->AddBatchWithTimeout(move(row_batch), 1000000)) { I believe this introduced a bug. The problem is that if the add times out, the caller should retain ownership of the pointer. I think one solution is to make AddBatchWithTimeout take an rvalue ref. Alternatively it could just take a pointer to the unique_ptr (which is maybe more explicit). -- To view, visit http://gerrit.cloudera.org:8080/6527 To unsubscribe, visit http://gerrit.cloudera.org:8080/settings Gerrit-MessageType: comment Gerrit-Change-Id: Ie18f57b0d3fe0052a8ccd361b6a5fcdf979d0669 Gerrit-PatchSet: 5 Gerrit-Project: Impala-ASF Gerrit-Branch: master Gerrit-Owner: Alex Behm <[email protected]> Gerrit-Reviewer: Alex Behm <[email protected]> Gerrit-Reviewer: Marcel Kornacker <[email protected]> Gerrit-Reviewer: Tim Armstrong <[email protected]> Gerrit-Reviewer: anujphadke <[email protected]> Gerrit-HasComments: Yes
