Package org.apache.flink.orc.writer

Class ThreadLocalClassLoaderConfiguration

java.lang.Object
org.apache.hadoop.conf.Configuration
org.apache.flink.orc.writer.ThreadLocalClassLoaderConfiguration
All Implemented Interfaces:
Iterable<Map.Entry<String,String>>, org.apache.hadoop.io.Writable
@Internal public final class ThreadLocalClassLoaderConfiguration extends org.apache.hadoop.conf.Configuration
Workaround for https://issues.apache.org/jira/browse/ORC-653.

Since the conf is effectively cached across Flink jobs, at least force the thread local classloader to avoid classloader leaks.
