      Description

      Similar to IMPALA-5090 we should investigate and more clearly understand the table-loading failure modes when various RPCs to external services fail.
      We should be careful to log enough information when handling various RPC failures during table loading. For example, if the NN is overloaded and a table fails to load as a result, we should log relevant HDFS client configuration option about retries/timeouts etc.

      Similar improvements apply to our interaction with Sentry and the Hive Metastore.
