Subject [jira] [Commented] (ACCUMULO-700) Improve iterator configuration for MapReduces
Date Wed, 15 Aug 2012 21:01:40 GMT


Billie Rinaldi commented on ACCUMULO-700:

If we configure iterators using, say, comma-separated base64-encoded representations of IteratorSettings,
a potential disadvantage is that the iterator information will no longer be readable in the
job configuration.  Does anyone need this to remain readable?

> 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.
