- updating java to 3.7 - added pet set example - adding pet set for Cassandra e2e tests - changed service as we do not want a lb service, as we are running C* - updated docs fixing headers and adding exception for run.sh adding documentation, thank god for reflog Did not mean to commit that as the README ... fixing fixing problems in README fixing more problems in README more README tweaks munge updates updating examples_test for PetSet in Cassandra examples updating petset to no use better security context
