-----------------------------------------
Summary: Remove redundant enum NNHAStatusHeartbeat.State
Key: HDFS-4268
URL: https://issues.apache.org/jira/browse/HDFS-4268
Project: Hadoop HDFS
Issue Type: Bug
Components: namenode
Affects Versions: 2.0.2-alpha
Reporter: Konstantin Shvachko
NNHAStatusHeartbeat.State is redundant and can be replaced with commonly used
enum HAServiceState.
We should also consistently use HAServiceState to check if the state is ACTIVE
or STANDBY rather than using {{instanceof}}.
