Fix table.jsp in regards to splitting a region/table with an optional splitkey
------------------------------------------------------------------------------
Key: HBASE-3462
URL: https://issues.apache.org/jira/browse/HBASE-3462
Project: HBase
Issue Type: Improvement
Components: master
Affects Versions: 0.90.0
Reporter: Lars George
Priority: Minor
Fix For: 0.90.1
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
{quote}
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.
{quote}
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
{code}
2011-01-21 15:37:24,340 INFO org.apache.hadoop.hbase.client.HBaseAdmin: No
server in .META. for csfsef; pair=null
{code}
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.
