Thanks for fixing this, it should help a lot.

PS2, Line 191:     ExecutorMembershipSnapshot.update(req);
Removing the indirection makes sense. Can we go further and just not do the JNI 
call at all when it's not a coordinator (i.e. skip calling 
SendClusterMembershipToFrontend()) be/src/runtime/exec-env.cc
