Hello everyone. I'm running some queries on hive but I can see that when the bar reach 100% starts running once again but in a next stage. What these stages mean? anyone know?

They query execution is more a sequence of stages. It can be MR stages or FS ops or MR stages. For metastore, you may find operators like FileOperator, SelectOperator or FileSinkOperator. For MR stages, you may have parts like mapping table aliases with Map Operator tree and Reduce operator tree, etc.


Hope that helps.
