-----------------------------------
Summary: Move BlockStoragePolicy name's constants from
HdfsServerConstants.java to HdfsConstants.java
Key: HDFS-8811
URL: https://issues.apache.org/jira/browse/HDFS-8811
Project: Hadoop HDFS
Issue Type: Improvement
Reporter: Vinayakumar B
Assignee: Vinayakumar B
Currently {{HdfsServerConstants.java}} have following constants,
{code} String HOT_STORAGE_POLICY_NAME = "HOT";
String WARM_STORAGE_POLICY_NAME = "WARM";
String COLD_STORAGE_POLICY_NAME = "COLD";{code}
and {{HdfsConstants.java}} have the following
{code} public static final String MEMORY_STORAGE_POLICY_NAME = "LAZY_PERSIST";
public static final String ALLSSD_STORAGE_POLICY_NAME = "ALL_SSD";
public static final String ONESSD_STORAGE_POLICY_NAME = "ONE_SSD";{code}
It would be better to move all these to one place HdfsConstants.java, which
client APIs also could access since this presents in hdfs-client module.
