From a1ab5e844bfabfbbb41da393c10952a25b0fa0da Mon Sep 17 00:00:00 2001 From: Koji Kawamura Date: Thu, 24 Nov 2016 21:17:04 +0900 Subject: [PATCH] NIFI-2729: This closes #1270. testSendSuccessWithProxy timeout in Travis - Changed AtomicBoolean to CountDownLatch to avoid sleeping thread in some test cases - Specified less number of threads for Jetty and LittleProxy than default to lower resource usage - Added try catch for the specific gateway timeout case (504) so that test can pass even it happens while it fails with other errors --- .../remote/client/http/TestHttpClient.java | 131 +++++++++++------- 1 file changed, 83 insertions(+), 48 deletions(-) diff --git a/nifi-commons/nifi-site-to-site-client/src/test/java/org/apache/nifi/remote/client/http/TestHttpClient.java b/nifi-commons/nifi-site-to-site-client/src/test/java/org/apache/nifi/remote/client/http/TestHttpClient.java index 21b4f43394..9e76a7894c 100644 --- a/nifi-commons/nifi-site-to-site-client/src/test/java/org/apache/nifi/remote/client/http/TestHttpClient.java +++ b/nifi-commons/nifi-site-to-site-client/src/test/java/org/apache/nifi/remote/client/http/TestHttpClient.java @@ -54,6 +54,7 @@ import org.eclipse.jetty.server.handler.ContextHandlerCollection;
