> Persist Block Storage Policy in FSImage and Edit Log
> ----------------------------------------------------
>
> Key: HDFS-7076
> URL: https://issues.apache.org/jira/browse/HDFS-7076
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: balancer, namenode
> Reporter: Jing Zhao
> Assignee: Jing Zhao
> Attachments: HDFS-7076.000.patch, HDFS-7076.001.patch, editsStored

>
> Currently block storage policies are loaded from a XML file. This may lead to
> policy inconsistency if the content of the XML gets modified or if the XML
> file is replaced by mistake. Thus it is better to persist policies in
> editlog/fsimage.
> Specifically we plan to do the following in this jira:
> # Add new DistributedFileSystem API for getting all the existing storage
> policies
> # Add new DistributedFileSystem/HdfsAdmin API for adding a new storage
> policy. The new storage policy is then persisted in editlog and later fsimage
> while checkpointing.
