   I am not sure if this is the right thing to do or should be the default 
behavior. I guess if the pruner fails, there could be some silly bug in pruner 
itself or the metadata / data used to prune could be malformed (e.g negative 
partition IDs). So imo the query should fail. 
   
   Also simply logging the exception and letting the query run without pruning 
does not help the oncall / admin / dev in fixing the root cause. For example, 
query on partitioned table can suddenly degrade in performance and someone will 
have to sift through logs to find the real reason. There should be some of 
metric if we really want this behavior
