Stumbled across this new feature in HDFS: https://issues.apache.org/jira/browse/HDFS-6634. Has anyone else seen this? Basically it would let you be notified whenever files are changed in HDFS, similar (but not exactly like) inotify. This sounds like it could let us update externally indexed data on HDFS incrementally doesn't it?...
Just a random thought. -Ian
