---------------------------------------
Summary: Nodetool uses cassandra-env.sh MAX_HEAP_SIZE if set
Key: CASSANDRA-12739
URL: https://issues.apache.org/jira/browse/CASSANDRA-12739
Project: Cassandra
Issue Type: Bug
Components: Tools
Reporter: Brad Vernon
Attachments: cass-21_tools_xmx.patch, cass-22_tools_xmx.patch,
cass-3x_tools_xmx.patch
Nodetool and other bash startup scripts load cassandra-env.sh variables
including MAX_HEAP_SIZE as part of CASSANDRA-10679. If cassandra-env.sh has
MAX_HEAP_SIZE set to any value the default heap size needed for the cassandra
tool to run is overridden.
This is a problem if the using a large heap in C* i.e. 16-32G due to each
instance of nodetool or other tool will allocate large heap regardless of need
and could exceed the total RAM available on the system.
Patch removes the check for MAX_HEAP_SIZE being set and uses the default heap
size needed for each tool.
