> Key: CALCITE-3324
> URL: https://issues.apache.org/jira/browse/CALCITE-3324
> Project: Calcite
> Issue Type: Bug
> Affects Versions: 1.20.0
> Reporter: Robert Yokota
> Priority: Major
> Labels: pull-request-available
>
> I encountered an infinite loop when submitting DDL from a remote Avatica
> driver (using sqlline) against a LocalService wrapping CalciteMetaImpl.
> I was able to debug the issue and verified a fix.
> The problem was that in CalciteMetaImpl.prepareAndExecute, the updateCount is
> not being passed to the MetaResultSetImpl constructor. Instead, the
> updateCount is always set to -1. This incorrectly instructs the remote
> Avatica driver to fetch results when there aren't any, which causes it to
> loop.
> By fixing the CalciteMetaImpl.prepareAndExecute method to set the updateCount
> in MetaResultSetImpl, I was able to fix the infinite loop.
