Synopsis

nodetool <options> stop -- <compaction_type>

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`	Remote JMX agent username.
`compaction type`	Supported types are COMPACTION, VALIDATION, CLEANUP, SCRUB, VERIFY, INDEX_BUILD.
`--`	Separates an option from an argument that could be mistaken for a option.

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 stop 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.
Valid compaction types: COMPACTION, VALIDATION, CLEANUP, SCRUB, INDEX_BUILD

Description

Stops all compaction operations from continuing to run. This command is typically used to stop a compaction that has a negative impact on the performance of a node. After the compaction stops, Cassandra continues with the remaining operations in the queue. Eventually, Cassandra restarts the compaction.

In Cassandra 2.2 and later, a single compaction operation can be stopped with the -id option. Run nodetool compactionstats to find the compaction ID.
