Mikhail Antonov updated HBASE-7171:
-----------------------------------
Attachment: HBASE-7171.patch
Here's draft patch. Added two new pages, region details and storefile details.
Some notes (cc [~stack], [~enis]):
- regarding using "logical" api to traverse store files (think
region.getStores().get('cfname').getStoreFiles() ) vs "physical" (traversing fs
assuming certain physical layout and linking to NN-style printout) I think
first one would be easier to maintain and cleaner going forward? What do we
need to display on region page. Memstore params (besides current size, what
else? timestamps, snapshot info? File information - size, lmd, what else is of
interest given the limited horizontal space.
- for now I just used quick and dirty approach when clicking at store file
name link simply invokes another java process (via 'hbase hfile...') and
redirects the output to the page. Is this information what we want to see at
this store file details page (assuming that browsing individual cells is not
something I'm doing now, that needs more thinking)? If this information is
kind of what we want here, then to avoid having to call another process I can
change HFilePrettyPrinter, pull KeyValueStatsCollector out of it, and a bit
more refactoring would be needed there.
