* V1 - improve parallelism of zookeeper based segment change processing * Create zk nodes in batches. Address code review comments. Introduce various configs. * Add documentation for the newly added configs * Fix test failures * Fix more test failures * Remove prinstacktrace statements * Address code review comments * Use a single queue * Address code review comments Since we have a separate load peon for every historical, just having a single SegmentChangeProcessor task per historical is enough. This commit also gets rid of the associated config druid.coordinator.loadqueuepeon.curator.numCreateThreads * Resolve merge conflict * Fix compilation failure * Remove batching since we already have a dynamic config maxSegmentsInNodeLoadingQueue that provides that control * Fix NPE in test * Remove documentation for configs that are no longer needed * Address code review comments * Address more code review comments * Fix checkstyle issue * Address code review comments * Code review comments * Add back monitor node remove executor * Cleanup code to isolate null checks and minor refactoring * Change param name since it conflicts with member variable name |

Apache Druid (incubating)
Apache Druid (incubating) is a high performance analytics data store for event-driven data.
Disclaimer: Apache Druid is an effort undergoing incubation at The Apache Software Foundation (ASF), sponsored by the Apache Incubator. Incubation is required of all newly accepted projects until a further review indicates that the infrastructure, communications, and decision making process have stabilized in a manner consistent with other successful ASF projects. While incubation status is not necessarily a reflection of the completeness or stability of the code, it does indicate that the project has yet to be fully endorsed by the ASF.

Community
The Druid community is in the process of migrating to Apache by way of the Apache Incubator. Eventually, as we proceed along this path, our site will move from http://druid.io/ to https://druid.apache.org/.
Community support is available on the druid-user mailing list(druid-user@googlegroups.com), which is hosted at Google Groups.
Development discussions occur on dev@druid.apache.org, which you can subscribe to by emailing dev-subscribe@druid.apache.org.
We also have a couple people hanging out on IRC in #druid-dev on
irc.freenode.net.
