Answer 1

我找到了运行zookzeeper时出现此错误的解决方案

Here is step 
1)Locate the start script of zookeeper under the bin folder of kafka
2)Open the file
3)Locate the below code in the file

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
    export KAFKA_HEAP_OPTS="-Xmx512M -Xms512M"

4) Replace the step 3 code with below one

if [ "x$KAFKA_HEAP_OPTS" = "x" ]; then
    KAFKA_HEAP_OPTS="-Xmx512M -Xms512M"
    # Add the required JVM options
    export KAFKA_HEAP_OPTS="$KAFKA_HEAP_OPTS -XX:+UnlockExperimentalVMOptions -XX:+UseG1GC"
The error has gone next time when u run this command. 
Note : If you facing issue while running zookeeper , kafka or topic . You can use this code and replace it with respective start script Let me know if you face any issue
