> Support non-volatile storage class memory(SCM) in HDFS cache directives

> Key: HDFS-13762
> URL: https://issues.apache.org/jira/browse/HDFS-13762
> Project: Hadoop HDFS
> Issue Type: Improvement
> Components: caching, datanode
> Reporter: Sammi Chen
> Assignee: Wei Zhou
> Priority: Major
> Attachments: HDFS-13762.000.patch, HDFS-13762.001.patch,
> HDFS-13762.002.patch, HDFS-13762.003.patch, HDFS-13762.004.patch,

>
> No-volatile storage class memory is a type of memory that can keep the data
> content after power failure or between the power cycle. Non-volatile storage
> class memory device usually has near access speed as memory DIMM while has
> lower cost than memory. So today It is usually used as a supplement to
> memory to hold long tern persistent data, such as data in cache.
> Currently in HDFS, we have OS page cache backed read only cache and RAMDISK
> based lazy write cache. Non-volatile memory suits for both these functions.
> This Jira aims to enable storage class memory first in read cache. Although
> storage class memory has non-volatile characteristics, to keep the same
> behavior as current read only cache, we don't use its persistent
> characteristics currently.
