Note:
  • 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, the remaining operations in the queue are continued. Eventually, the compaction is restarted.

In the DataStax Distribution of Apache Cassandra (DDAC), a single compaction operation can be stopped with the -id option. Run nodetool compactionstats to find the compaction ID.
