stack commented on HBASE-14925:
-------------------------------
To be clear, the sed hackery above is not meant to replace the original wish
for a simple way of listing regions and servers. The hard part I think is how
to format the output (taking into consideration that keys may have binary
content..). The list suggestion with a means of specifying how to do the output
seems good ([~huaxiang]?)
Would be cool too if rather than solve the explicit ask here, instead we did
some generic changes -- such as making it so it easy to iterate row results in
the shell to do with the result as you wish -- so it was easy to satisfy
requests like those of the original posters. E.g: being able to iterate in the
shell on the rows returned out of a Scan:
{code}
hbase> for result in "hbase:meta".scan({FILTER, [COLUMNS]) do
puts(results.get('info:server') + " " + results.get("info:regioninfo")) end
{code}
... or some such ... but even just writing the above out, it is ugly... in
ruby+hbase shell DSL... and it is incomplete not writing escaped strings....
So scratch this last suggestion (smile) at least for now.

> I am going through the hbase shell commands to see if there is anything I can
> use to get all the regions info just for a particular table. I don’t see any
> such command that provides me that information.
> It would be better to have a command that provides region info, start key,
> end key etc taking a table name as the input parameter. This is available
> through HBase UI on clicking on a particular table's link
> A tool/shell command to get a list of regions for a table or all tables in a
> tabular structured output (that is machine readable)
