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. -- This message was sent by Atlassian JIRA (v6.1#6144)
