Class AbstractHadoopProcessor.ExtendedConfiguration

java.lang.Object

org.apache.hadoop.conf.Configuration

org.apache.nifi.processors.hadoop.AbstractHadoopProcessor.ExtendedConfiguration

All Implemented Interfaces:

Iterable<Map.Entry<String,String>>, org.apache.hadoop.io.Writable

Enclosing class:

AbstractHadoopProcessor

static class AbstractHadoopProcessor.ExtendedConfiguration
extends org.apache.hadoop.conf.Configuration

Extending Hadoop Configuration to prevent it from caching classes that can't be found. Since users may be adding additional JARs to the classpath we don't want them to have to restart the JVM to be able to load something that was previously not found, but might now be available. Reference the original getClassByNameOrNull from Configuration.
