Subject [jira] [Commented] (HBASE-7171) Click on a region in UI and get a listing of hfiles in HDFS and summary of memstore content; click on an HFile and see its content

stack commented on HBASE-7171:
------------------------------

bq.  but HDFS nav code in servlet running inside NN would be of little value, since it's showing
one 'current' folder at a time

You are right.

I think we need two 'views'. One view would be a table of:

/hbase/data/abc/def/ghi/abcdefghijklmnopqrstuvwxyz

Another view would be tables/familes/regions view (though what if the table has a million
regions?).

For the latter view, currently you could do listing of HDFS content but when we moved over
to the new fs layout, this view would be gotten by querying the master for what are the tables,
families, etc., and ultimately what files are in a Store. It would become a pretty pivotal
piece since you won't be able to get it anymore doing a dfs -lsr /hbase

bq. show some stats, or show output similar to what 'hbase hfile' shows?...

For sure. For a start this would be a million miles ahead of what we have now.

bq. ...so not sure we want to display actual user data from tables in it?

There is that concern, yes. Would have to default not showing anything. Would be sweet though
if could browse... but that could come later.
