[jira] [Commented] (CONNECTORS-1519) CLIENTPROTOCOLEXCEPTION is
thrown with 2.10 -> ES 6.x.y
[ https://issues.apache.org/jira/browse/CONNECTORS-1519?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16870351#comment-16870351 ]

--------------------------------------------
I spent some time looking at this and added some debugging to the current version. I believe the issue is this is what comes back with more logging:
{code:java}
DEBUG 2019-06-22T10:36:16,378 (Thread-1440) - ClientProtocol Exception: ClientProtocolException
DEBUG 2019-06-22T10:36:16,378 (Thread-1440) - ClientProtocol Exception: null
DEBUG 2019-06-22T10:36:16,378 (Thread-1440) - ClientProtocol Cause: Cannot retry request with a non-repeatable request entity.{code}
and I saw that I got a org.apache.http.client.NonRepeatableRequestException exception. Looking into it I found this:
/* * If you try to PUT from a stream to a server that uses Digest * authorization, the operation will fail, because the authorization * handling will cause * "org.apache.http.client.NonRepeatableRequestException: Cannot retry request with a non-repeatable request entity." * Semi-precise explanation of this issue: Issuing a PUT from a stream leads * to the httpclient library using a non-repeatable (streamed) entity. But * the authorization process makes the library to repeat the request (1. try * unauthorized, 2. server say 401 Unauthorized, use Digest, 3. client * retries with Digest, but this will fail, due to the nature of * non-repeatable streamed entity). * * the workaround is to convert streamed (non-repeatable) entity to * self-contained (repeatable). */
So I think that if xpack is enabled, then it bombs because the HttpEntity is converted in a stream and can't be repeated.
I'm looking at this and potentially will have a fix.
