Dan Hecht has uploaded a new patch set (#2). ( http://gerrit.cloudera.org:8080/10811 )
Change subject: IMPALA-7207: make Coordinator::exec_state_ an atomic enum ...................................................................... IMPALA-7207: make Coordinator::exec_state_ an atomic enum That allows us to avoid taking the lock in cases where only the exec_state_ field needs to be read (as opposed to needing to read both exec_state_ and exec_status_). In particular, it avoids the lock on the non-terminating paths, which is the common case.
