> Right now, we always share Hadoop classes between Spark side and the metastore client side (HiveClientImpl). However, it is possible that the Hadoop used by the metastore client is in a different version of Hadoop. Thus, in this case, we cannot share Hadoop classes. Once we disable sharing Hadoop classes, we cannot pass a Hadoop Configuration to HiveClientImpl because Configuration will be loaded by different classloaders.
