Haohui Mai commented on HDFS-5196:
----------------------------------
{code}
+ public String getSnapshottableDirs() throws IOException
{code}
Please return a plain object instead of a string. Please see HDFS-6013 for more
details.
I also suggest dropping changes of the jsp side in this patch, leaving changes
related to the new UI in this jira.
