NOTE
- The above guidance has been derived from looking at AMS disk utilization in actual clusters.
- The ACTUAL numbers have been obtained by observing an actual cluster with the basic services (HDFS, YARN, HBase) installed along with Storm, Kafka and Flume.
- Kafka and Flume generate metrics only while a job is running. If those services are being used, additional disk space is recommended.
