wuzhanpeng opened a new issue #2889:
URL: https://github.com/apache/bookkeeper/issues/2889
**BUG REPORT**
***Describe the bug***
Can not execute `ReadLogMetadata` with file name in bookkeeper shell.
The parameter of `ReadLogMetadata` that cannot be parsed as numbers will
eventually be converted to `0.log` due to `logId` in `ReadLogMetadataFlags` is
never initialized.
***To Reproduce***
Steps to reproduce the behavior:
Execute command:
`bin/bookkeeper shell readlogmetadata XXX.log`
Then we can see:
```
18:48:42.192 [main] INFO
org.apache.bookkeeper.tools.cli.commands.bookie.ReadLogMetadataCommand - Print
