[Hidetomi]

I'm annoyed by prompt error messages.
help me.

• I deleted /tmp/confluent.* and tried it, but the result is the same.
• The result is the same even if you change to OpenJDK11.
• "zombie" zookeeper does not exist.
• execute bash(./bin/zookeeper-server-start ./etc/kafka/zookeeper.properties.). It Is starting with zookeeper-server-start is fine.
• I read to issue Confluent CLI says stack is down, even if it's not #48 and Error message on start can be more useful... #33, But no hint was found there.
• option -vvvv is not print.

execute.
