Contributor guide
Research direction
Start by running the Cassandra job with ARGS='-Dtest=**/graphdb/astyanax/*' and reproduce AstyanaxGraphTest>JanusGraphTest.testIndexUpdatesWithReindexAndRemove at line 1500. Inspect the test and its reindex/remove sequence to determine why the result is sometimes zero; done means the test no longer flakes and the expected assertion passes consistently.
