ronan stokes commented on HBASE-14925:
--------------------------------------
Its useful to consider why some one would use this command when looking at the
variations and what parameters might be required
Some examples:
- planning to take a node of out of service => in this case its useful to see
what regions are on a specific server in order to determine what you need to
move
- diagnosing skew or region imbalance => in this case, what you need is a
breakdown of the regions by server - but you are interested in the counts,sizes
by server along with read and write rates
- preparing to manually balance a table => need to filter by table name
- informational purposes only => just need to ensure that data is up to date
> Develop HBase shell command/tool to list table's region info through command
> line

> 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)
