“log4j.properties was unexpected at this time” while trying to start Zookeeper in windows

问题

I am using kafka stream download from Confluent (http://www.confluent.io/product/kafka-streams/).

I am following the instructions to run Zookeeper and Kafka on Windows. But while I try to start ZooKeeper using the command D:\Softwares\confluent-3.0.1\bin\windows>zookeeper-server-start.bat ./etc/kafka/zookeeper.properties, I get the error

D:\Softwares\confluent-3.0.1\bin\windows../../etc/kafka/log4j.properties was unexpected at this time.

If I check the "zookeeper-server-start.bat" file the commands look ok and is like below.There also exists log4j.properties file under directory confluent-3.0.1\etc\kafka

IF [%1] EQU [] (
    echo USAGE: %0 zookeeper.properties
    EXIT /B 1
  )


SetLocal
IF ["%KAFKA_LOG4J_OPTS%"] EQU [""] (
    if exists %~dp0../../etc/kafka/log4j.properties (
        set KAFKA_LOG4J_OPTS=-Dlog4j.configuration=file:%~dp0../../etc/kafka/log4j.properties
    ) else (
        set KAFKA_LOG4J_OPTS=-Dlog4j.configuration=file:%~dp0../../config/log4j.properties
    )
)

IF ["%KAFKA_HEAP_OPTS%"] EQU [""] (
    set KAFKA_HEAP_OPTS=-Xmx512M -Xms512M
)

I was getting same error when I placed kafka downloaded distribution in C:\Program Files (x86). Moving kafka downloaded distribution to some other drive other then c drive worked for me.

Find below working commands: D:\kafka_2.12-2.2.0\kafka_2.12-2.2.0>bin\windows\zookeeper-server-start.bat config/zookeeper.properties

Kafka was downloaded from it's official site:
