> Memory leak in Parquet async reader when Snappy fails
> -----------------------------------------------------

> Key: DRILL-5160
> URL: https://issues.apache.org/jira/browse/DRILL-5160
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.9.0
> Reporter: Paul Rogers
> Assignee: Kunal Khatua

> See the details in DRILL-5157. The Parquet async reader uses the Snappy
> library. If the call into Snappy fails (in my case, due to missing dependency
> management in the Drill pom.xml file), the Parquet reader fails (as it
> should.)
> Unfortunately, the Parquet reader leaks memory which cause
> {{IllegalStateException}} errors in production, assertion failures in unit
> tests.
> To reproduce this the easy way (to avoid the need to undo the fix for
> DRILL-5157 in Snappy dependencies), use Drill's exception injector in inject
> an exception at the line where we call into Snappy (See DRILL-5157 for
> details.)
> Set a breakpoint exception for {{IllegalStateException}} you will see the
> memory leak.
