Note:
- If a username and password for RMI authentication are set explicitly in the cassandra-env.ps1 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.
