Tsuyoshi Ozawa commented on HDFS-9084:
--------------------------------------
[~raviprak] thank you for the very neat feature! It works well with small files
or directories. I'm also okay to postpone the trimming down of columns to
another JIRA.
I think, however, we have one problem. If the number of directories increases,
the Web UI gets slow down because the client-side rendering take CPU time. I
had an experiment as follows:
{code}
$ cat /dev/urandom | tr -dc 'a-zA-Z0-9' | fold -w 16 | head -n 150000 >
lists.txt
$ cat lists.txt | hdfs dfs -mkdir
<It takes 50 sec to render the result>
{code}
This can be happens when Hive create lots partition. My suggestion is to create
upper limit of the entries to be rendered like Google's search result. What do
you think?
