Description
With PROVIDED storage (HDFS-9806), HDFS can address data stored in external storage systems. Caching this data, locally, in HDFS can speed up subsequent accesses to the data – this feature is especially useful when accesses to the external store have limited bandwidth/higher latency. This JIRA is to add this feature in HDFS.
