Dmitry Konstantinov created CASSANDRA-21804:
-----------------------------------------------
Summary: cassandra-env.sh may fail if Cassandra directory path
contains Xmx, Xms or Xmn
Key: CASSANDRA-21804
URL: https://issues.apache.org/jira/browse/CASSANDRA-21804
Project: Apache Cassandra
Issue Type: Bug
Components: Local/Scripts
Reporter: Dmitry Konstantinov
cassandra-env.sh decides whether heap flags were set with plain substring
searches: echo $JVM_OPTS | grep -q Xmx and grep -q Xms
(conf/cassandra-env.sh:89-92 on trunk). Xmx matches the path and Xms doesn't,
so it prints "Please set or unset -Xmx and -Xms flags in pairs" and exits 1
For example, we may get "run-python-dtest.XmxjVU/" directory as a part of our
DTest. ccm rewrites each node's GC logging option to an absolute path
(<node>/logs/gc.log). So the directory name ends up in JVM_OPTS.
