Patch Set 18: (1 comment) http://gerrit.cloudera.org:8080/#/c/10158/18/be/src/runtime/coordinator.cc File be/src/runtime/coordinator.cc: http://gerrit.cloudera.org:8080/#/c/10158/18/be/src/runtime/coordinator.cc@457 PS18, Line 457: ret_status > exec_status_ is protected by the lock, so the copy is necessary.
