Subject [jira] [Commented] (HDFS-7228) Add an SSD policy into the default BlockStoragePolicySuite
Date Tue, 14 Oct 2014 03:19:34 GMT

Tsz Wo Nicholas Sze commented on HDFS-7228:
-------------------------------------------

Since LAZY_PERSIST has a _, I think ALLSSD and ONESSD should also have a _.

+1 patch looks good other then that.

> Currently in the default BlockStoragePolicySuite, we've defined 4 storage policies: LAZY_PERSIST,
HOT, WARM, and COLD. Since we have already defined the SSD storage type, it will be useful
to also include a SSD related storage policy in the default suite.
