Subject [jira] [Commented] (ACCUMULO-700) Improve iterator configuration for MapReduces
Date Thu, 16 Aug 2012 01:27:38 GMT


Josh Elser commented on ACCUMULO-700:

I would see no reason not to Writable the settings. We got bit by such issues back in 1.3
land with the old InputFormat.

Could expose a static method or main() which calls a toString on the serialized IteratorSetting
via bin/accumulo to satisfy David's request.

> The InputFormatBase currently uses AccumuloIterator and AccumuloIteratorOption configuration
objects to serialize iterator information for MapReduce.  These objects predate IteratorSetting,
which is now used to configure iterators.  We should just make IteratorSetting Writable so
it can be used directly for serializing iterator information.
