> Project: Apache HAWQ
> Issue Type: Bug
> Components: Hcatalog, PXF
> Affects Versions: 2.0.0.0-incubating
> Reporter: Oleksandr Diachenko
> Assignee: Goden Yao
> Labels: performance
> Fix For: backlog
>
>
> Reproduce Steps:
> {code}
> select count(*) from hcatalog.default.hivetable;
> {code}
> sometimes, this query will hang and we see from pxf logs that Hive thrift

> After a restart of PXF agent, this query goes through without issues.
