Akila Wajirasena commented on GIRAPH-745:
-----------------------------------------
In addition we cannot use both {{EdgeOutputFormat}} and {{VertexOutputFormat}}
in the same time. Because according to this method {{BspOutputFormat}} will
return only {{VertexOutputCommiter}} even if both output formats use.
{code}
public OutputCommitter getOutputCommitter(TaskAttemptContext context)
throws IOException, InterruptedException {
ImmutableClassesGiraphConfiguration conf =
new ImmutableClassesGiraphConfiguration(context.getConfiguration());
if (!conf.hasVertexOutputFormat() && !conf.hasEdgeOutputFormat()) {
LOG.warn("getOutputCommitter: Returning " +
"ImmutableOutputCommiter (does nothing).");
return new ImmutableOutputCommitter();
}
if (conf.hasVertexOutputFormat()) {
return conf.createWrappedVertexOutputFormat().getOutputCommitter(context);
} else {
return conf.createWrappedEdgeOutputFormat().getOutputCommitter(context);
}
}
{code}
I tested this with hive output formats and edge output will be written
correctly only if we don't have a vertex output format.
> add support for EdgeOutputFormat also for giraph-hive
