Backport of https://github.com/apache/hadoop/commit/7dc166ddc7fa524d842c77c0d6e83dde6d13dc54 Trunk PR: https://github.com/apache/hadoop/pull/6022 Description: Address JDK bug JDK-8314978 related to handling of HTTP 100 responses. https://bugs.openjdk.org/browse/JDK-8314978 In the AbfsHttpOperation, after sendRequest() we call processResponse() method from AbfsRestOperation. Even if the conn.getOutputStream() fails due to expect-100 error, we consume the exception and let the code go ahead. This may call getHeaderField() / getHeaderFields() / getHeaderFieldLong() after getOutputStream() has failed. These invocation all lead to server calls. This commit aims to prevent this. If connection.getOutputStream() fails due to an Expect-100 error, the ABFS client does not invoke getHeaderField(), getHeaderFields(), getHeaderFieldLong() or getInputStream(). getResponseCode() is safe as on the failure it sets the responseCode variable in HttpUrlConnection object. -- This is an automated message from the Apache Git Service.
