Change subject: IMPALA-3245: Fix crash with global filters when NUM_NODES=1 ...................................................................... IMPALA-3245: Fix crash with global filters when NUM_NODES=1 This patch disables global filters when NUM_NODES=1, to avoid a crash where the UpdateFilter() path expected a CountingBarrier to be set up which was only initialised on the multi-backend path. Alternative approaches include downgrading the global filters to local ones (since there's only one fragment), but the complexity in return for the performance gain does not seem worth it for this relatively little-used feature.
