nodetool rebuild

Rebuilds data by streaming from other nodes.

Synopsis

nodetool [(-h <host> | --host <host>)] [(-p <port> | --port <port>)]
     [(-pw <password> | --password <password>)]
     [(-pwf <passwordFilePath> | --password-file <passwordFilePath>)]
     [(-u <username> | --username <username>)] rebuild [--] <src-dc-name>
     [-dc <source_dc>

Table 1. Options
Short	Long	Description
`-h`	`--host`	Hostname or IP address
`-p`	`--port`	Port number
`-pwf`	`--password-file`	Password file path
`-pw`	`--password`	Password
`-u`	`--username`	User name
`--`	Separates an option from an argument that could be mistaken for a option.

Other options are:


Short	Long	Description
`-dc`	--dcs	The name of the datacenter that Cassandra uses as the source for streaming. Cassandra rebuilds from any datacenter. If a datacenter is not specified, Cassandra chooses at random.
`-ts`	`--tokens`	Token ranges, specify in this format: `(start_token_1,end_token_1],(start_token_2,end_token_2],...(start_token_n,end_token_n]`.

Description

This command operates on multiple nodes in a cluster. The rebuild tool only streams data from a single source replica when rebuilding a token range.

If rebuild fails because some token ranges cannot be retrieved, you can rebuild selectively by using the -ts or --token option to specify a list of tokens, or one or more token ranges.

Attention: If nodetool rebuild is interrupted before completing its process, it cannot be restarted from the point of failure. If you run rebuild again, it starts from the beginning.
