> Key: CASSANDRA-6404
> URL: https://issues.apache.org/jira/browse/CASSANDRA-6404
> Project: Cassandra
> Issue Type: Improvement
> Components: Tools
> Reporter: Sam Tunnicliffe
> Assignee: Sam Tunnicliffe
> Priority: Minor
> Fix For: 1.2.12, 2.0.3
>
> Attachments: 0001-Set-javaagent-when-running-tools-in-bin.patch

>
> The combination of CASSANDRA-6107 & CASSANDRA-6293 has lead to a number of
> the tools shipped in bin/ to display the following warnings when run:
> {code}
> ERROR 15:21:47,337 Unable to initialize MemoryMeter (jamm not specified as
> javaagent). This means Cassandra will be unable to measure object sizes
> accurately and may consequently OOM.
> WARN 15:21:47,506 MemoryMeter uninitialized (jamm not specified as java
> agent); KeyCache size in JVM Heap will not be calculated accurately. Usually
> this means cassandra-env.sh disabled jamm because you are u
> {code}
> Although harmless, these are a bit disconcerting. The simplest fix seems to
> be to set the javaagent switch as we do for the main C* launch.
