Haohui Mai commented on HADOOP-11875:
-------------------------------------
bq. Hamlet is easy to use from Java code. What do you want, us to switch to JSP?
In HDFS, switching from JSP to JMX + HTML5 has shown various improvement on
user experience, productivity and security.
bq. It's used in downstream YARN apps, which is not just done out of laziness,
but to handle the proxy renaming stuff, plus escaping of text.
Can you be more concrete on what needs to be fixed?
