Maintenance mode for cdh 5.4.3

Hi,

 

We are trying to upgrade our hardware and rack bandwidth. Need to upgrade one rack per time. We are in CDH 5.4.3. Upgrading one rack would take 90 mins. Wondering If we use maintenance mode during upgrading, will name node still send job to node manager in rack or reading data from maintenance rack?

 

Thanks

 

Luke
