Gian Merlino 513bc76252 RTR: Ensure that there is only one cleanup task scheduled for a worker at once. 
This is accomplished by making sure that scheduleTasksCleanupForWorker is only called
from the PathChildrenCache event thread, having it cancel existing cleanup tasks when
it adds a new one, and having tasks check on finish that the thing they are removing
from the task list is actually themselves.

Druid

Druid is a distributed, column-oriented, real-time analytics data store that is commonly used to power exploratory dashboards in multi-tenant environments.

Druid excels as a data warehousing solution for fast aggregate queries on petabyte sized data sets. Druid supports a variety of flexible filters, exact calculations, approximate algorithms, and other useful calculations.

Druid can load both streaming and batch data and integrates with Samza, Kafka, Storm, and Hadoop.
