             Summary: Windows Quickstart script fails
                 Key: KAFKA-7998
                 URL: https://issues.apache.org/jira/browse/KAFKA-7998
             Project: Kafka
          Issue Type: Bug
    Affects Versions: 2.1.0
            Reporter: Dieter De Paepe


Following the [Quickstart |http://kafka.apache.org/quickstart]guide on windows, I received an error in the script to start Zookeeper:
{noformat}
The input line is too long.
The syntax of the command is incorrect.{noformat}
The cause is in the long CLASSPATH being constructed, resulting in a very long string:
{noformat}
for %%i in ("%BASE_DIR%\libs\*") do (
	call :concat "%%i"
)

...

:concat
IF not defined CLASSPATH (
  set CLASSPATH="%~1"
) ELSE (
  set CLASSPATH=%CLASSPATH%;"%~1"
){noformat}

A simple fix is to change the "kafka-run-class.bat" as follows (for all similar loops):
{noformat}for %%i in ("%BASE_DIR%\libs\*") do (
	call :concat "%%i"
){noformat}
should become
{noformat}call :concat "%BASE_DIR%\libs\*"{noformat}
