Jing Zhao created HDFS-5327:
-------------------------------
Summary: Rename StandbyException to FailoverException
Key: HDFS-5327
URL: https://issues.apache.org/jira/browse/HDFS-5327
Project: Hadoop HDFS
Issue Type: Improvement
Affects Versions: 3.0.0
Reporter: Jing Zhao
Assignee: Jing Zhao
Priority: Minor
After HDFS-5291, client's RPC level can determine whether to retry the same
server or failover to another server based on the two types of exception:
# The new introduced RetriableException indicating that the server is
temporarily unavailable and clients can retry.
# The old StandbyException indicating that clients can failover and try another
server.
In this context, since the term "standby" only tells one scenario (active +
standby), we may want to rename the StandbyException to FailoverException to
make it more generic.
