Looks like others have reported the same problem before. See http://grokbase.com/t/cloudera/hue-user/137axc7mpm/upload-file-over-64mb-via-hue and https://issues.cloudera.org/browse/HUE-2782.
I do agree with HUE-2782's "we need to intentionally limit upload file size" as this is a web app and probably isn't the right tool when we are getting to some file size. Glad to hear "hdfs dfs -put" is working fine.
On the flipside, I did test this out a bit with the HDFS Files "Ambari View" that is available with the 2.4 Sandbox and as you can see from the screenshot, user maria_dev was able to load a 80MB file to her home directory via the web interface as well as a 500+MB file. I'm sure this Ambari View also has some upper limit.
Maybe it is time to start thinking about moving from Hue to Ambari Views??
