Karan Mehta updated HBASE-14925:
--------------------------------
Release Note:
Added a shell command 'list_regions' for displaying the table's region info
through command line.
List all regions for a particular table as an array and also filter
them by server name (optional) as prefix
and maximum locality (optional). By default, it will return all the
regions for the table with any locality.
The command displays server name, region name, start key, end key, size
of the region in MB, number of requests
and the locality. The information can be projected out via an array as
third parameter. By default all these information
is displayed. Possible array values are SERVER_NAME, REGION_NAME,
START_KEY, END_KEY, SIZE, REQ and LOCALITY. Values
are not case sensitive. If you don't want to filter by server name,
pass an empty hash / string as shown below.
Examples:
hbase> list_regions 'table_name'
hbase> list_regions 'table_name', 'server_name'
hbase> list_regions 'table_name', {SERVER_NAME => 'server_name',
LOCALITY_THRESHOLD => 0.8}
hbase> list_regions 'table_name', {SERVER_NAME => 'server_name',
LOCALITY_THRESHOLD => 0.8}, ['SERVER_NAME']
hbase> list_regions 'table_name', {}, ['SERVER_NAME', 'start_key']
hbase> list_regions 'table_name', '', ['SERVER_NAME', 'start_key']
> 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)
