So we have some code (a custom input format for data persisted in accumulo with a custom indexing scheme (geospatial/n-dimensional)):
https://github.com/ngageoint/geowave/blob/GEOWAVE-84-squash/geowave-accumulo/src/main/java/mil/nga/giat/geowave/accumulo/mapreduce/input/GeoWaveInputFormat.java#L355 The intent behind this was to provide better locality and split information since we have a bit more application specific knowledge available than the general use case. I'm pretty sure there's no other way to get this locality information other than using the TableLocator class. The arguments + ordering change for TCredentials to Credentials and the method signature from getInstance() to getLocator() are the two things breaking our 1.5.1 -> 1.6.x compatibility. (specifically: https://github.com/apache/accumulo/commit/99da5641c28784c7b717cce6749673863c2ec8cf#diff-c45768534f53d5455cc05c75676fb871R49 https://github.com/apache/accumulo/commit/446a37a9795f2df7adc841154ca05add79cf286e#diff-c45768534f53d5455cc05c75676fb871R95 ) It's pretty obvious from the diff these were intentional - so no joy there in accidental changes that could be fixed. Are we just to far down in the weeds, and are going to have to deal with supporting multiple versions/breaking changes (via refactoring, dropping support, or maven-munge maybe), or is this class/methods/signatures expected to be pretty stable now? (Or is there a better/more supported way of getting tablet locality information?)
