nodetool checktokenmetadata
Compares the endpointState from gossip with the TokenMetadata on the node, and displays any mismatches between these two views of the cluster topology.
To prevent possible data loss for a node that contains mismatching cluster topology information, restart the node.

Syntax diagrams and code samples use one or more of these styles to mark placeholders for variable values. Replace placeholders with a valid option or your own user-defined value. In CQL statements, angle brackets are required to enclose data types in a set, list, map, or tuple.
Separate the data types with a comma.
For example: In Search CQL statements, angle brackets are used to identify the entity and literal value to overwrite the XML element in the schema and |

Square brackets surround optional command arguments. Do not type the square brackets. |

Parentheses identify a group to choose from. Do not type the parentheses. |
|
A pipe separates alternative elements. Type any one of the elements. Do not type the pipe. |

Indicates that you can repeat the syntax element as often as required. |

Single quotation marks must surround literal strings in CQL statements.
Use single quotation marks to preserve upper case.

Separate command line options from command arguments with two hyphens. This syntax is useful when arguments might be mistaken for command line options. |
Options
If an option has a short and long form, both forms are given, separated by a comma.
- -h, --host hostname
-
The hostname or IP address of a remote node or nodes. When omitted, the default is the local machine.
- -p, --port jmx_port
-
The JMX port number.
- -pw, --password jmxpassword
-
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.
Examples
Compare the cluster topology views on the node
To find mismatches between the endpointState from gossip and the TokenMetadata on the node, run the following command:
nodetool checktokenmetadataIf the topology views match on a node, the command returns no output.
If the topology view of the cluster between the two sources does not match on a node, the result indicates the mismatched node.
For example, the following response shows a mismatch on node 192.0.2.2.
To fix this mismatch issue, restart the node.
Mismatch on : 192.0.2.2
