Chris Douglas commented on HADOOP-4575:
---------------------------------------
The core changes look fine. The contrib changes are OK for now, but in the
future:
* If there were a limit on even the number of elements in the cache, checking
that condition is less expensive than iterating over all the users in the cache
for each insertion.
* Where there is not a compatibility requirement for previous versions, the
code duplication in ProxyHttpServer should be reduced. In particular, 0.20
should have a version with the "right" abstractions.
* No information would be an improvement over a reserved HTTP error code.
Something generic, like 400, perhaps?
Compiling against trunk, I got no errors when applying only the patch. Are the
jars in lib.tgz supposed to go into src/contrib/hdfsproxy/lib ?

> Currently, an HDFS cluster itself exposes an HTTP/HTTPS interface for reading
> files (i.e., HFTP/HSFTP). However, there is a need for an HTTPS proxy server
> running independently from the cluster and serving data to users who
> otherwise can't access the cluster directly. This proxy will authenticate its
> users via SSL certificates and implements the HSFTP interface for reading
> files.
