Zhijie Shen commented on MAPREDUCE-4064:
----------------------------------------
The bug still happens on trunk. I did some investigation:
1. When generating proxyTrackingUrl from originalTrackUrl, the original host
section is replaced by "[proxy host]:[port]/proxy/[application id]", while the
following sections are kept. For example,
{code}
http://192.168.1.108:19888/jobhistory/job/job_1404265212778_0003
{code}
in translated into
{code}
https://0.0.0.0:8088/proxy/application_1404265212778_0003/jobhistory/job/job_1404265212778_0003
{code}
2. On the other hand, in WebAppProxyServlet, "[application id]" section is used
to search for originalTrackingURL, and the following part is appended to the
end of originalTrackingURL. For example, we will see
{code}
http://192.168.1.108:19888/jobhistory/job/job_1404265212778_0001/jobhistory/job/job_1404265212778_0001
{code}
Fortunately, JHS will simply ignore the additional sections, such that we won't
see an apparent error.
Therefore, with the current logic, whenever AM provides a tracking url that has
more sections after host:port, it will be finally translated into an url that
has duplicate sections after host:port.
It seems we should either hide all the rest sections in proxyTrackingURL, or
not append them when WebAppProxyServlet recovers the originalTrackingURL.
