      Starting in 4.4 Map-Reduce does not support the nonAtomic option. The output is always nonAtomic and the option is ignored. Tests with tenant migration behaviour that check the output of a Map-Reduce might fail and thus should be tagged tenant_migration_incompatible.

      mr_reduce.js and mr_merge.js are two of those tests but there might be more.
