Change subject: IMPALA-7213, IMPALA-7241: Port ReportExecStatus() RPC to use KRPC ...................................................................... Patch Set 14: Code-Review+1 (6 comments) I wasn't able to do a particularly deep review but I don't think that should hold things up. Looks great at a high level and I'm excited to get it in. Had a few minor suggestions but nothing critical. http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/runtime/coordinator-backend-state.cc File be/src/runtime/coordinator-backend-state.cc: http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/runtime/coordinator-backend-state.cc@275 PS14, Line 275: unique_lock<mutex> lock(lock_); Can we document the lock order in coordinator.h (which already references ExecSummary::lock) http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/runtime/fragment-instance-state.h File be/src/runtime/fragment-instance-state.h: http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/runtime/fragment-instance-state.h@177 PS14, Line 177: Monontonically Typo: Monotonically http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/runtime/fragment-instance-state.h@179 PS14, Line 179: int32_t report_seq_no_ = 0; I imagine you already thought about this and concluded that overflows were not possible, but I'm wondering why not just make it an int64_t anyway so that it's super-obvious that it's not possible. http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/runtime/fragment-instance-state.cc File be/src/runtime/fragment-instance-state.cc: http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/runtime/fragment-instance-state.cc@396 PS14, Line 396: DFAKE_SCOPED_LOCK(report_status_lock_); This is kind of cool. http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/testutil/in-process-servers.cc File be/src/testutil/in-process-servers.cc: http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/testutil/in-process-servers.cc@51 PS14, Line 51: ; Extra semicolon http://gerrit.cloudera.org:8080/#/c/10855/14/be/src/testutil/in-process-servers.cc@51 PS14, Line 51: FLAGS_krpc_port = I guess we can't set this to 0 to automatically choose an ephemeral port?
