Description

HiveConf is a SessionState level object. Some ACID related logic makes changes to it (which are meant to be per query) but become per SessionState.

See SemanticAnalyzer.checkAcidConstraints()
Also note HiveConf.setVar(conf, HiveConf.ConfVars.DYNAMICPARTITIONINGMODE, "nonstrict");
in UpdateDeleteSemancitAnalzyer

alangates, do you know of other cases or ideas on how to deal with this differently?

SortedDynPartitionOptimizer.process() is the place to have the logic to do conf.setBoolVar(ConfVars.HIVEOPTSORTDYNAMICPARTITION, false); on per query basis
