> HDFS read cache persistence support
> -----------------------------------
>
> Key: HDFS-14740
> URL: https://issues.apache.org/jira/browse/HDFS-14740
> Project: Hadoop HDFS
> Issue Type: Improvement
> Reporter: Feilong He
> Assignee: Feilong He
> Priority: Major
> Attachments: HDFS-14740.000.patch
>
>
> In HDFS-13762, persistent memory is enabled in HDFS centralized cache
> management. Even though persistent memory can persist cache data, for
> simplifying the implementation, the previous cache data will be cleaned up
> during DataNode restarts. We propose to improve HDFS persistent memory (PM)
> cache by taking advantage of PM's data persistence characteristic, i.e.,
> recovering the cache status when DataNode restarts, thus, cache warm up time
> can be saved for user.
