This patch does a few things: 1) Move the metadata tests into their own folder under tests/. I think it's useful to loosely categorize them so it's easier to run a subset of the tests that are most useful for the changes you are making. 2) Reduce the test vectors for query_tests. We should have identical coverage in the daily exhaustive runs but the normal runs should be much better. In particular, deemphasizing scanner tests since that code is more stable now. 3) Misc test cleanup/consolidate python test files/etc. Change-Id: I03c2f34877aed192c2a50665bd5e15fa85e12f1e Reviewed-on: http://gerrit.sjc.cloudera.com:8080/3831 Tested-by: jenkins Reviewed-by: Nong Li <nong@cloudera.com>
