------------------------------------------
Summary: Allow only suitable storage policies to be set on striped
files
Key: HDFS-10473
URL: https://issues.apache.org/jira/browse/HDFS-10473
Project: Hadoop HDFS
Issue Type: Sub-task
Components: namenode
Reporter: Uma Maheswara Rao G
Assignee: Uma Maheswara Rao G
Currently existing storage policies are not suitable for striped layout files.
This JIRA proposes to reject setting storage policy on striped files.
Another thought is to allow only suitable storage polices like ALL_SSD.
Since the major use case of EC is for cold data, this may not be at high
importance. So, I am ok to reject setting storage policy on striped files at
this stage. Please suggest if others have some thoughts on this.
Thanks [~zhz] for offline discussion on this.
