Dinesh Chitlangia commented on HDFS-14012:
------------------------------------------

[~yzhangal] In which version are you seeing this?

In trunk, I see the following:
{panel:title=hadoop/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/io/retry/RetryInvocationHandler.java}
{code:java}
else {
 LOG.warn("A failover has occurred since the start of call #" + callId
 + " " + proxyInfo.getString(method.getName()));
}{code}
{panel}
