             Summary: Extend KMS related exceptions that get mapped to ConnectException 
                 Key: HADOOP-18245
                 URL: https://issues.apache.org/jira/browse/HADOOP-18245
             Project: Hadoop Common
          Issue Type: Bug
          Components: kms
            Reporter: Ritesh H Shukla


Based on production workload, we found that it is not enough to map just SSLHandshakeException to ConnectException in Loadbalancing KMS Client but that needs to be extended to SSLExceptions and SocketExceptions. 

Sample JDK code that can raise these exceptions.
|/**|
|| * Read the initial handshake records.|
|| */|
||private int readHandshakeRecord() throws IOException {|
||while (!conContext.isInboundClosed()) {|
||try {|
||Plaintext plainText = decode(null);|
||if ((plainText.contentType == ContentType.HANDSHAKE.id) &&|
||conContext.isNegotiated) {|
||return 0;|
||}|
||} catch (SSLException \||
||InterruptedIOException \| SocketException se) {|
||// Don't change exception in case of timeouts or interrupts|
||// or SocketException.|
||throw se;|
||} catch (IOException ioe) {|
||throw new SSLException("readHandshakeRecord", ioe);|
||}|
||}|
|||
||return -1;|
||}|
