---------------------------------
[~cheersyang] {quote}For the comment about object store user API key
information, I am not sure about this point, could you please elaborate.{quote}
In [Hadoop AWS Integration
document|https://hadoop.apache.org/docs/current/hadoop-aws/tools/hadoop-aws/index.html],
we need to specify fs.s3a.access.key and fs.s3a.secret.key to connect to aws
account. The same principal applies to swift fs, and other object store.
Therefore, the CSI specification should include ability to pass the key
information to connect to object store. In the current specification, it is
also missing source storage information.
Propagation options are required to make sure multiple mount of the same source
storage system can be shared or exclusive mount. Without this defined, it
might be troublesome for source storage system to decide the locking mechanism.

>
> The Container Storage Interface (CSI) is a vendor neutral interface to bridge
> Container Orchestrators and Storage Providers. With the adoption of CSI in
> YARN, it will be easier to integrate 3rd party storage systems, and provide
> the ability to attach persistent volumes for stateful applications.
