I'm going to be upgrading our CM/CDH 5.14 cluster to 5.16. I've noticed a new step named "Hue Document cleanup" (https://www.cloudera.com/documentation/enterprise/upgrade/topics/ug_cdh_upgrade.html#cdh_upgrade5)
Looking at the estimate given (1 minute per 1000 rows), this would take around 3 hours at best on my cluster (MySQL backend).
Can these scripts be run with theh cluster still operational and will if affect anything? Ideally I would like to run this outside of my maintenance window to save time, but can only do so if the cluster will still be in a usable state.
