Parameters#

Parameter	Details
`-dc <specific_dc>`, `--in-dc <specific_dc>`	Use `-dc` to repair specific datacenters
`-dcpar`, `--dc-parallel`	Use `-dcpar` to repair data centers in parallel.
`-et <end_token>`, `--end-token <end_token>`	Use `-et` to specify a token at which repair range ends
`-full`, `--full`	Use `-full` to issue a full repair.
`-h <host>`, `--host <host>`	Node hostname or ip address
`-hosts <specific_host>`, `--in-hosts <specific_host>`	Use `-hosts` to repair specific hosts
`-j <job_threads>`, `--job-threads <job_threads>`	Number of threads to run repair jobs. Usually this means number of CFs to repair concurrently. WARNING: increasing this puts more load on repairing nodes, so be careful. (default: 1, max: 4)
`-local`, `--in-local-dc`	Use `-local` to only repair against nodes in the same datacenter
`-p <port>`, `--port <port>`	Remote jmx agent port number
`-pl`, `--pull`	Use `--pull` to perform a one way repair where data is only streamed from a remote node to this node.
`-pr`, `--partitioner-range`	Use `-pr` to repair only the first range returned by the partitioner
`-pw <password>`, `--password <password>`	Remote jmx agent password
`-pwf <passwordFilePath>`, `--password-file <passwordFilePath>`	Path to the JMX password file
`-seq`, `--sequential`	Use `-seq` to carry out a sequential repair
`-st <start_token>`, `--start-token <start_token>`	Use `-st` to specify a token at which the repair range starts
`-tr`, `--trace`	Use `-tr` to trace the repair. Traces are logged to `system_traces.events`.
`-u <username>`, `--username <username>`	Remote jmx agent username
`--`	This option can be used to separate command-line options from the list of argument, (useful when arguments might be mistaken for command-line options
`[<keyspace> <tables>...]`	The keyspace followed by one or many tables

Running repair on Cassandra

Run repair on a particular partition range.

nodetool repair -pr
