On a 2PM combo stack with query stats enabled, one of the PMs returned an error when queries is executed

Build tested: 1.0.4-1 beta

I setup a combo stack with 2 PMs, then I changed parameters in Columnstore.xml to enable query stats:
<CrossEngineSupport>
<Host>localhost</Host>
<Port>3306</Port>
<User>root</User>
<Password/>
</CrossEngineSupport>
<QueryStats>
<Enabled>Y</Enabled>
</QueryStats>

After the above change, PM2 worked as expected and queries are being logged in infinidb_querystats.querystats table, but PM2 would return an warning. The executed query was not log in either of the PMs.
MariaDB [mytest]> select count from orders;

MariaDB [mytest]> select * from infinidb_querystats.querystats;
