Hyukjin Kwon resolved SPARK-9203.
---------------------------------
Resolution: Incomplete
> Make filesystem pluggable in BlockStore and BlockManager
> --------------------------------------------------------
>
> Key: SPARK-9203
> URL: https://issues.apache.org/jira/browse/SPARK-9203
> Project: Spark
> Issue Type: Improvement
> Components: Block Manager
> Reporter: Alexey Goncharuk
> Priority: Major
> Labels: bulk-closed
>
> I was looking through the code in order to understand better how RDD is
> persisted to Tachyon off-heap filesystem. It looks like that the Tachyon
> filesystem is hard-coded and there is no way to switch to another in-memory
> filesystem. I think it would be great if the implementation of the
> BlockManager and BlockStore would be able to plug in another filesystem.
> For example, Apache Ignite also has an implementation of in-memory filesystem
> which can store data in on-heap and off-heap formats. It would be great if it
> could integrate with Spark.
