nodetool getendpoints

Returns the endpoints that own the partition key.

Returns the endpoints that own the partition key. See Partition keys.

Synopsis

nodetool [connection_options] getendpoints
[--] keyspace_name table_name partition_key
Table 1. Legend
Syntax conventions Description
UPPERCASE Literal keyword.
Lowercase Not literal.
Italics Variable value. Replace with a valid option or user-defined value.
[ ] Optional. Square brackets ( [ ] ) surround optional command arguments. Do not type the square brackets.
( ) Group. Parentheses ( ( ) ) identify a group to choose from. Do not type the parentheses.
| Or. A vertical bar ( | ) separates alternative elements. Type any one of the elements. Do not type the vertical bar.
... Repeatable. An ellipsis ( ... ) indicates that you can repeat the syntax element as often as required.
'Literal string' Single quotation ( ' ) marks must surround literal strings in CQL statements. Use single quotation marks to preserve upper case.
{ key:value } Map collection. Braces ( { } ) enclose map collections or key value pairs. A colon separates the key and the value.
<datatype1,datatype2> Set, list, map, or tuple. Angle brackets ( < > ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.
cql_statement; End CQL statement. A semicolon ( ; ) terminates all CQL statements.
[ -- ] Separate the command line options from the command arguments with two hyphens ( -- ). This syntax is useful when arguments might be mistaken for command line options.
' <schema> ... </schema> ' Search CQL only: Single quotation marks ( ' ) surround an entire XML schema declaration.
@xml_entity='xml_entity_type' Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrconfig files.

Definition

The JMX password for authenticating with secure JMX. If a password is not provided, you are prompted to enter one.
-pwf, --password-file jmx_password_filepath
The filepath to the file that stores JMX authentication credentials.
-u, --username jmx_username
The username for authenticating with secure JMX.

Command arguments

--
Separates an option from an argument that could be mistaken for a option.
key
Partition key of the end points you want to get.
keyspace_name
The keyspace name.
table_name
The table name.

Examples

Get endpoints that own partition key

Note: The partitioner returns a token for the key. DSE will return an endpoint regardless of whether data exists on the identified node for that token.

Consider the following table created in the cycling keyspace, which uses a primary key of race_year and race_name:

CREATE TABLE cycling.rank_by_year_and_name (
    race_year int,
    race_name text,
    rank int,
    cyclist_name text,
    PRIMARY KEY ((race_year, race_name), rank)
) WITH CLUSTERING ORDER BY (rank ASC);
INSERT INTO cycling.rank_by_year_and_name (race_year, race_name, cyclist_name, rank) VALUES (2015, 'Tour of Japan - Stage 4 - Minami > Shinshu', 'Benjamin PRADES', 1);
INSERT INTO cycling.rank_by_year_and_name (race_year, race_name, cyclist_name, rank) VALUES (2015, 'Tour of Japan - Stage 4 - Minami > Shinshu', 'Adam PHELAN', 2);
INSERT INTO cycling.rank_by_year_and_name (race_year, race_name, cyclist_name, rank) VALUES (2015, 'Tour of Japan - Stage 4 - Minami > Shinshu', 'Thomas LEBAS', 3);
INSERT INTO cycling.rank_by_year_and_name (race_year, race_name, cyclist_name, rank) VALUES (2015, 'Giro d''Italia - Stage 11 - Forli > Imola', 'Ilnur ZAKARIN', 1);
INSERT INTO cycling.rank_by_year_and_name (race_year, race_name, cyclist_name, rank) VALUES (2015, 'Giro d''Italia - Stage 11 - Forli > Imola', 'Carlos BETANCUR', 2);
INSERT INTO cycling.rank_by_year_and_name (race_year, race_name, cyclist_name, rank) VALUES (2014, '4th Tour of Beijing', 'Phillippe GILBERT', 1);
INSERT INTO cycling.rank_by_year_and_name (race_year, race_name, cyclist_name, rank) VALUES (2014, '4th Tour of Beijing', 'Daniel MARTIN', 2);
INSERT INTO cycling.rank_by_year_and_name (race_year, race_name, cyclist_name, rank) VALUES (2014, '4th Tour of Beijing', 'Johan Esteban CHAVES', 3);

Run nodetool getendpoints with a value from the partition key:

nodetool getendpoints cycling rank_by_year_and_name "2014"

Result is the IP address of the replica that owns the partition key:

10.255.100.150

Get endpoints that own partition key for full primary key

nodetool getendpoints cycling rank_by_year_and_name "2014:4th Tour of Beijing"

Result is the IP address of the replica that owns the partition key:

10.255.100.150
