Description

Information logs in zkServer.sh script being redirected to stderr (2) stream

/opt/apache-zookeeper-3.7.0-bin/bin
bash-4.4$ cat zkServer.sh | grep "&2"
  echo "ZooKeeper JMX enabled by default" >&2
    echo "ZooKeeper remote JMX Port set to $JMXPORT" >&2
    echo "ZooKeeper remote JMX authenticate set to $JMXAUTH" >&2
    echo "ZooKeeper remote JMX ssl set to $JMXSSL" >&2
    echo "ZooKeeper remote JMX log4j set to $JMXLOG4J" >&2
      echo "ZooKeeper remote JMX Hostname set to $JMXHOSTNAME" >&2
    echo "JMX disabled by user request" >&2
echo "Using config: $ZOOCFG" >&2
    echo "Usage: $0 [--config <conf-dir>] {start|start-foreground|stop|version|restart|status|print-cmd}" >&2
bash-4.4$ 

and in container logs we could see these logs are coming as stderr

2023-01-10T08:16:34.393866602+01:00 stderr F ZooKeeper JMX enabled by default
2023-01-10T08:16:34.395496162+01:00 stderr F Using config: /var/lib/zookeeper/config-dynamic/zoo.cfg
 

Expectation:

Information logs should coming in stdout.
