Package org.apache.flink.orc.writer

Class 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.
