> Centralized cache management in HDFS

> Key: HDFS-4949
> URL: https://issues.apache.org/jira/browse/HDFS-4949
> Project: Hadoop HDFS
> Issue Type: New Feature
> Components: datanode, namenode
> Affects Versions: 3.0.0, 2.3.0
> Reporter: Andrew Wang
> Assignee: Andrew Wang

>
> HDFS currently has no support for managing or exposing in-memory caches at
> datanodes. This makes it harder for higher level application frameworks like
> Hive, Pig, and Impala to effectively use cluster memory, because they cannot
> explicitly cache important datasets or place their tasks for memory locality.
