 Drill saves storage plugin configurations in a temporary directory (embedded mode) or in ZooKeeper (distributed mode). For example, on Mac OS X, Drill uses /tmp/drill/sys.storage_plugins to store storage plugin configurations. The temporary directory clears when you reboot. Copy storage plugin configurations to a secure location to save them when you run drill in embedded mode.
