Thanks Larry for getting back on this.This will not be a blocker. We will use
the long path for the time being.
Do you think, it will be done by Q1,16?Regards,Mohammad

Hi Mohammad -
This issue is really hard to track down.I assume it has actually been broken
for quite a while.
I am curious just how important this is for your deployment and usecases.
I'd like to get to closing down other issues for the 0.11.0 release rather than
have this issue delay the release - if it is something that we can get by with
as a known issue for another release.
Thoughts?
thanks,
--larry

Let me play around with it and see what is going on there.Will probably get
back to you tomorrow about it.

Hi,
I set "default.app.topology.name" in gateway-site.xml to "uber" (my default
topology name). It worked fine if I gave the full URL. The command looks like
this "curl http://<KNOX_GW_URL>/gateway/ uber/webhdfs/v1/?op=GETHOMEDIR
ECTORY'". However, when I tried with command "curl
http://<KNOX_GW_URL>/webhdfs/ v1/?op=GETHOMEDIRECTORY'". I got the HTTP error
code 500. I looked into gateway.log file and found quite a few error related to
rewrite. The exact error messages are shown below:
Error message
2016-11-30 00:39:51,565 ERROR hadoop.gateway (UrlRewriteProcessor.java:rewr
ite(169)) - Failed to rewrite URL: http://<KNOX_GW_URL>/webhdfs/v

http://<KNOX_GW_URL>/webhdfs/v 1/?op=GETHOMEDIRECTORY, direction: IN via rule:
WEBHDFS/webhdfs/inbound/nameno de/root, status: FAILURE
After that, I modified the webhdfs/2.4.0/rewrite.xml by rewriting the following
pattern and it worked for short URL but long URL faces the same issue.
Original:
<rule dir="IN" name="WEBHDFS/webhdfs/inbound/ namenode/root"
pattern="*://*:*/**/webhdfs/{v ersion}/?{**}"> <rewrite
template="{$serviceUrl[WEBHDFS ]}/{version}/?{**}"/> </rule>
Modified :
<rule dir="IN" name="WEBHDFS/webhdfs/inbound/ namenode/root"
pattern="*://*:*/webhdfs/{vers ion}/?{**}"> <rewrite
template="{$serviceUrl[WEBHDFS ]}/{version}/?{**}"/> </rule>
Overall, the rewrite pattern may be the issue. We will need to support for both
short and long URL. May be, we can add multiple rewrite rules for each route in
service.xml.Is there any other cleaner way which may work for all cases such as
webhdfs, yarn, hive, UIs etc?
