Major Description
After HBASE-3328 and HBASE-3437 went in there is also the table.jsp that needs updating to support the same features. Also, at the same time update the wording, for example
This action will force a split of all eligible regions of the table, or, if a key is supplied, only the region containing the given key. An eligible region is one that does not contain any references to other regions. Split requests for noneligible regions will be ignored.
I think it means it splits either all regions (that are splittable) or a specific one. It says though "the region containing the given key", that seems wrong in any event. Currently we do a split on the tablename when nothing was specified or else do an internal get(region), which is an exact match on the rows in .META.. In other words you need to match the region name exactly or else it fails. It reports it has accepted the request but logs internally
2011-01-21 15:37:24,340 INFO org.apache.hadoop.hbase.client.HBaseAdmin: No server in .META. for csfsef; pair=null
Error reporting could be better but because of the async nature this is more difficult, yet it would be nice there is some concept of a Future to be able to poll the result if needed.
Finally, when you go back to the previous page after submitting the split the entered values show up in the "compact" input fields, at least on my Chrome. The inputs in both forms are named the same so it seems to confuse it. This could be improved a lot by making the landing page reload the main one automatically or refresh on reload instead of submitting the request again.
