Description

A ton of logs with this Utilities - PLAN PATH = hdfs://localhost:59527/.../apache-hive/itests/qtest-spark/target/tmp/scratchdir/stakiar/6ebceb49-7a76-4159-9082-5bba44391e30/hive_2018-05-14_07-28-44_672_8205774950452575544-1/-mr-10006/bf14c0b5-a014-4ee8-8ddf-fdb7453eb0f0/map.xml

Seems it print multiple times per task exception, not sure where it is coming from, but its too verbose. It should be changed to DEBUG level. Furthermore, given that we are using Utilities#getBaseWork anytime we need to access a MapWork or ReduceWork object, we should make the method slightly more efficient. Right now it borrows a Kryo from a pool and does a bunch of stuff to set the classloader, then it checks the cache to see if the work object has already been created. It should check the cache before doing any of that.
