Summary: Avoid unnecessary edit log for setStoragePolicy() and
setReplication()
Key: HDFS-11291
URL: https://issues.apache.org/jira/browse/HDFS-11291
Project: Hadoop HDFS
Issue Type: Bug
Reporter: Surendra Singh Lilhore
Assignee: Surendra Singh Lilhore
We are setting the storage policy for file without checking the current policy
of file for avoiding extra getStoragePolicy() rpc call. Currently namenode is
not checking the current storage policy before setting new one and adding edit
logs. I think if the old and new storage policy is same we can avoid set
operation.
