[I] Confused output while use comand line option --help to show bookie usage [bookkeeper]
tmzk1005 opened a new issue, #4240:
URL: https://github.com/apache/bookkeeper/issues/4240
**BUG REPORT**
***Describe the bug***
When execute `bin/bookkeeper bookie -help` to see the command line usage. The output is like this:
```
2024-03-22T11:07:36,335 - ERROR - [main:Main@242] - Error parsing command line arguments :
java.lang.IllegalArgumentException: null
at org.apache.bookkeeper.server.Main.parseArgs(Main.java:113) ~[org.apache.bookkeeper-bookkeeper-server-4.18.0-SNAPSHOT.jar:4.18.0-SNAPSHOT]

usage: BookieServer [options]
[-c <arg>] [-h] [-hp <arg>] [-i <arg>] [-j <arg>] [-l <arg>] [-m
<arg>] [-p <arg>] [-r] [-withAutoRecovery] [-z <arg>]
BookieServer provide an interface to start a bookie with configuration
file and/or arguments.The settings in configuration file will be overwrite
by provided arguments.
Options including:
-c,--conf <arg> Configuration for Bookie Server
-h,--help Print help message
-hp,--httpport <arg> bookie http port exported
-i,--indexdirs <arg> bookie index directories
-j,--journal <arg> bookie journal directory
-l,--ledgerdirs <arg> bookie ledgers directories
-m,--zkledgerpath <arg> Zookeeper ledgers root path
-p,--bookieport <arg> bookie port exported
-r,--readOnly Force Start a ReadOnly Bookie server
-withAutoRecovery Start Autorecovery service Bookie server
-z,--zkserver <arg> Zookeeper Server
Here is an example:
BookieServer -c bookie.conf -z localhost:2181 -m /bookkeeper/ledgers -p
3181 -j /mnt/journal -i "/mnt/index1 /mnt/index2" -l "/mnt/ledger1
/mnt/ledger2 /mnt/ledger3"
```
The usage information shows that option `--help` is supported, but there is some error log while using it.
This is not a big problem, only makes the user (especially newbie to bookkeeper like me) a little bit confused about the error log. I think just the normal usage information without error log would be better.
***To Reproduce***
execute `bin/bookkeeper bookie -help`
***Expected behavior***
Only normal usage information without error log.
