nodetool verify

Verify (check data checksum for) one or more tables.

Synopsis

nodetool [options] verify [(-e | --extended-verify)] [--] [<keyspace> <tables>...]

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

Note:

For tarball installations, execute the command from the install_location/bin directory.
If a username and password for RMI authentication are set explicitly in the cassandra-env.sh file for the host, then you must specify credentials.
nodetool verify operates on a single node in the cluster if -h is not used to identify one or more other nodes. If the node from which you issue the command is the intended target, you do not need the -h option to identify the target; otherwise, for remote invocation, identify the target node, or nodes, using -h.

Description

The nodetool verify command checks the data checksum for one or more specified tables. An optional argument, -e or --extended-verify, will verify each cell data, whereas without the option, only the SSTable checksums are verified.

Examples

nodetool -u cassandra -pw cassandra verify cycling cyclist_name

The location of the cassandra-env.sh file depends on the type of installation:

Package installations	/etc/cassandra/cassandra-env.sh
Tarball installations	`install_location`/conf/cassandra-env.sh
