/**
 * Override the default setup process to speed up bootstrap
 *
 * - disable JMX//from  w ww.j  a v a2  s  .  co m
 * - disable legacy schema migration
 * - no pre-3.0 hints migration
 * - no pre-3.0 batch entries migration
 * - disable auto compaction on all keyspaces (your test data should fit in memory!!!)
 * - disable metrics
 * - disable GCInspector
 * - disable mlock
 * - disable Thrift server
 * - disable startup checks (Jemalloc, validLaunchDate, JMXPorts, JvmOptions, JnaInitialization, initSigarLibrary, dataDirs, SSTablesFormat, SystemKeyspaceState, Datacenter, Rack)
 * - disable materialized view rebuild (you should clean data folder between each test anyway)
 * - disable the SizeEstimatesRecorder (estimate SSTable size, who cares for unit testing ?)
