nodetool rebuild

This command operates on a single node where the command is run. It streams data from multiple nodes in the specified datacenter. Use this command on each node after adding a datacenter to stream data to that node.

If nodetool rebuild is interrupted before completion, restart it by re-entering the command. The process resumes from the point at which it was interrupted.

Syntax conventions Description


Literal keyword.


Not literal.


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.


Set, list, map, or tuple. Angle brackets ( < > ) enclose data types in a set, list, map, or tuple. Separate the data types with a comma.


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.


Search CQL only: Identify the entity and literal value to overwrite the XML element in the schema and solrconfig files.


The short- and long-form options are comma-separated.

Connection options

-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.

Command arguments


Separates an option from an argument that could be mistaken for an option.

-c, --connections-per-host num_connections

Maximum number of connections per host for streaming. Overrides value of streaming_connections_per_host in cassandra.yaml.

-dc src_dc_names, --dcs src_dc_names

Comma-separated list of datacenters from which to stream.

  • src_dc_names - Datacenter names are case-sensitive. For example, dc-a,dc-b. To include a rack name, separate datacenter and rack name with a colon (:). For example, dc-a:rack1,dc-a:rack2.

  • when not set - The default is to pick any datacenter.

-ks, --keyspace keyspace_name, …​

Comma-separated list of one or more keyspaces. List only the keyspaces to include in the rebuild.

Do not include keyspaces that are not replicated across datacenters (for example, dsefs keyspaces, and keyspaces with local strategy).

-m, --mode mode
  • normal - conventional behavior, streams only ranges that are not already locally available

  • refetch - resets locally available ranges, streams all ranges but leaves current data untouched

  • reset - resets the locally available ranges, removes all locally present data (like a TRUNCATE), streams all ranges

  • reset-no-snapshot - (like reset) resets the locally available ranges, removes all locally present data (like a TRUNCATE), streams all ranges but prevents a snapshot even if auto_snapshot is enabled

When not specified, the default is normal.

-s, --sources source_ip_address

Comma-separated list of IP addresses from which to stream.

-ts, --tokens (start_token_1,end_token_1], (start_token_2,end_token_2], …​

Comma-separated list of token ranges, in this format (start_token_1,end_token_1],(start_token_2,end_token_2],(start_token_n,end_token_n]

-x, --exclude-sources exclude_source_IPs

Comma-separated list of IP addresses to exclude from streaming.

-xdc, --exclude-dcs exclude_dc_name

Comma-separated list of datacenters to exclude from streaming. For example, dc-a,dc-b. To include a rack name in the list, separate datacenter and rack name with a colon (:). For example, dc-a:rack1,dc-a:rack2.


Rebuild from any datacenter

nodetool rebuild

Rebuild from DC2

nodetool rebuild -dc DC2

Rebuild from DC2 and DC3
