--------------------------------------
Summary: spark.ui.reverseProxy=true leads to hanging communication to master
Key: SPARK-20853
URL: https://issues.apache.org/jira/browse/SPARK-20853
Project: Spark
Issue Type: Bug

spark.ui.reverseProxy=true

first of all any invocation of the spark master Web UI hangs forever locally (e.g. http://192.168.10.16:25001) and via external URL without any data received.
One, sometimes two spark applications succeed without error and than workers start throwing exceptions:

Caused by: java.io.IOException: Failed to connect to /192.168.10.16:25050
{quote}
The application dies during creation of SparkContext:
