------------------------------------------
Summary: Tools emit ERRORs and WARNINGs about missing javaagent
Key: CASSANDRA-6404
URL: https://issues.apache.org/jira/browse/CASSANDRA-6404
Project: Cassandra
Issue Type: Improvement
Components: Tools
Reporter: Sam Tunnicliffe
Priority: Minor
Fix For: 2.0.3, 1.2.12
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.
