org.apache.rocketmq.tools.command.SubCommandException: UpdateTopicSubCommand command failed

我在使用 ./mqadmin updateTopic -n localhost:9876 -t stock -c DefaultCluster
命令创建topic是报如下错误：
Java HotSpot™ 64-Bit Server VM warning: ignoring option PermSize=128m; support was removed in 8.0
Java HotSpot™ 64-Bit Server VM warning: ignoring option MaxPermSize=128m; support was removed in 8.0

解决办法是：
1.进入rocketmq的bin目录下：/var/www/rocketmq/rocketmq-all-4.4.0-bin-release/bin，
/var/www/rocketmq是我自己的安装路径。
2.用vim tools.sh打开tools.sh.在JAVA_OPT配置中，在-Djava.ext.dirs这一行的后面添加ext的路径，原配置如下

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn256m -XX:PermSize=128m -XX:MaxPermSize=128m"
JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext"
JAVA_OPT="${JAVA_OPT} -cp ${CLASSPATH}"

添加后：

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn256m -XX:PermSize=128m -XX:MaxPermSize=128m"
JAVA_OPT="${JAVA_OPT} -Djava.ext.dirs=${BASE_DIR}/lib:${JAVA_HOME}/jre/lib/ext:/usr/java/jdk1.8.0_65/jre/lib/ext"
JAVA_OPT="${JAVA_OPT} -cp ${CLASSPATH}"

添加之后再创建就可以了。
