Gian Merlino a14200d779 Index service support for early returns and choice of commit semantics. 
Task:
- Add TaskCallback to run method (for early returns)

TaskStatus:
- Remove CONTINUED status
- Add segmentsNuked (placeholder for future deletion support)
- Add more builder methods
- Add validations to constructor

TaskStorage:
- Add TaskStorageQueryAdapter, a concrete class that wraps TaskStorages and
  provides various read-only convenience methods
- Add getTask method for benefit of TaskStorageQueryAdapter

TaskQueue:
- Rename "done" to "notify"
- notify is responsible for deciding if we should commit
- Add optional commitRunnable to "notify", which gets called when it's time to commit
- Allow nextTasks and commits to run early (statusCode RUNNING)
- Move getStatus, collapseStatus functionality to TaskStorageQueryAdapter

README added DruidSetup.java and install/druid_setup.sh to run it for Druid ensemble setup (put properties to zk, create zk zpaths, prep db, and dump properties/paths in zk); property druid.zk.paths.base can establish a namespace for a druid ensemble allowing more than one ensemble to use the same zookeepers; this namespace is the base zpath prefix for paths with properties in the form druid.zk.paths.*Path which are normally set automatically now; if druid.zk.paths.*Path are explicitly set, then all of them must be set with absolute paths to ensure careful attention; ZkSetup is now deprecated, use DruidSetup instead; examples/twitter RealtimeStandaloneMain will exit properly now after a kill -15 (control-c or kill pid) instead of hanging on an unstopped daemon. 2012-11-06 00:16:27 -08:00
