> Reproduce Steps:
> {code}
> select count(*) from hcatalog.default.hivetable;
> {code}
> sometimes, this query will hang and we see from pxf logs that Hive thrift server cannot be connected from PXF agent. 
> While users can still visit hive metastore (through HUE) and execute the same query.
> After a restart of PXF agent, this query goes through without issues.
