classloader in org.apache.hadoop.hive.metastore.ObjectStore

[Qiang Wang]

class ObjectStore has a private member named 'classloader':

private ClassLoader classLoader;
{
        classLoader = Thread.currentThread().getContextClassLoader();
        if (classLoader == null) {
            classLoader = QueryStore.class.getClassLoader();
        }
}

But I can't find the place where it's used.

Anyone has an idea about this ?
