Sreenath Somarajapuram commented on TEZ-3288:
---------------------------------------------
bq. Why are we using 0 as a value which indicates an error ( generally speaking
0 is always meant to indicate success )? Is it something which the tez
framework uses or due the ember library?
Status 0 is how the browsers react when an URL is not reachable (Including
CORS). When it cannot communicate with the server is just sets the status code
as 0.
bq. Why not do the wiki and linking in a completely different jira just related
to the wiki
Have created TEZ-3300 for all the wiki work.
bq. To clarify on the current patch, are we ensuring that we display the
following: the end url being requested ( not a proxy url if a proxy is being
used ), proxy url if proxy url is being used in case there are issues with the
proxy, http error code if present, message/error response body from the http
response ?
- We would be displaying the proxy url. Mainly because the current proxy is not
passive. While bypassing the errors, there are many errors that would be
generated by the proxy.
- Also considering HA enabled systems, we might not be always able to give the
exact URL that is hit by the Ambari proxy.
