Xiao Chen commented on HADOOP-15609:
------------------------------------
Thanks [~knanasi] for filing the Jira and [~jojochuang] for the discussion.
I think this surfaces only after the recent HADOOP-14841 fix (it's masked as
EOFE before). [~daryn] also mentioned this in one occasion to me. While more
investigation should be done regarding how to handle SSL more effectively, it
makes sense to me to retry on these exceptions.
> Retry KMS calls when SSLHandshakeException occurs

> Issue Type: Improvement
> Components: common, kms

> KMS call should retry when javax.net.ssl.SSLHandshakeException occurs and
> FailoverOnNetworkExceptionRetry policy is used.
> For example in the following stack trace, we can see that the KMS Provider's
> connection is lost, an SSLHandshakeException is thrown and the operation is
> not retried:
