On a single instance mongod, each of the 5 commands checks for the existence of the "config" or "configdb" field in the command object. If it exists and is a string, then shardingState is set to initializing in ShardingState::initialize. However the initialization never succeeds and the InitializationState is left in "initializing". Which causes calls to while loops waiting on initializationState to never exit:

while (_getInitializationState() == InitializationState::kInitializing) {
            _initializationFinishedCondition.wait(lk);
}

This affects subsequent calls to move/merge/splitChunk, setShardVersion, _recvChunkStart and shutdown
