Eli Collins commented on HDFS-5194:
-----------------------------------

Dave,

Great writeup.  There's a lot of stuff here, might be easiest to have more 
bandwidth and discuss via phone.  Will try to rope in some of the people who 
worked on HDFS-2907.

Would the following times (this Friday or next Monday) work for people?  Please 
select what works for you here if you'd like to join:

I'll setup a webex and post notes from the discussion back here.

Thanks,
Eli

> The existing FsDatasetSpi interface is well-positioned to permit extending 
> Hadoop to run natively on non-traditional storage architectures.  Before this 
> can be done, however, a number of gaps need to be addressed.  This JIRA 
> documents those gaps, suggests some solutions, and puts forth a sample 
> implementation of some of the key changes needed.
