Description

This issue would rise if a RuntimeException is injected after mSorter is created but before it does its sort job

mSorter.setup(context, oContext.getAllocator(), getSelectionVector4(), this.container);
injector.injectUnchecked(context.getExecutionControls(), "priorSort");
mSorter.sort(this.container);

Detailed Information:
1. query:
select n_name from cp.`tpch/nation.parquet` order by n_name

2. data:
cp.`tpch/nation.parquet`

3. log:
java.lang.IllegalStateException: Failure while closing accountor. Expected private and shared pools to be set to initial values. However, one or more were not. Stats are
zone init allocated delta
private 0 0 0
