Chapter 18. Installing Apache Accumulo

Apache Accumulo is a highly scalable structured and distributed key/value store for high performance data storage and retrieval.


Accumulo requires HDFS and ZooKeeper to be running before starting. Password-less SSH must be configured between at least the Accumulo master and TabletServer machines. It is recommended that you run Network Time Protocol (NTP) within the cluster to keep node clocks in sync to avoid problems with automatically timestamped data.
