Summary: Support use of counters in InputFormats
Key: GIRAPH-995
URL: https://issues.apache.org/jira/browse/GIRAPH-995
Project: Giraph
Issue Type: Improvement
Reporter: Bruno Dumon
I'm working on a custom EdgeInputFormat where I'd like to use map reduce
counters. I've noticed these don't work, because the TaskAttemptContext
contains a DummyReporter.
This is because WrappedEdgeInputFormat.createEdgeReader() creates a different
TaskAttemptContext to pass to the my reader, I assume because of threadsafety
considerations.
I patched HadoopUtils.makeTaskAttemptContext() to support counters, but only in
case HADOOP_NON_JOBCONTEXT_IS_INTERFACE, because only in that case it possible
to pass on a StatusReporter to the TaskAttemptContextImpl.
