Hakim > Labels: test > Fix For: Future > > > Commit Id# : bd8ac4fca03ad5043bca27fbc7e0dec5a35ac474 > We have seen this issue happen with the below steps > 1. Clear out the zookeeper > 2. Update the storage plugin using the rest API on one of the node > 3. Submit 10 queries concurrently > With randomized foreman node selection, the node executing the query might > not have the updated storage plugins info.
