BUG: print mkdir failed log

[xunliu]

When I execute ./launch-playground.sh script.

playground-hive        | mkdir: `/user/iceberg/': No such file or directory
playground-hive        | OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
playground-hive        | mkdir: `/user/iceberg/warehouse': No such file or directory
playground-hive        | OpenJDK 64-Bit Server VM warning: ignoring option MaxPermSize=256m; support was removed in 8.0
playground-hive        | chmod: `/user/iceberg/warehouse/': No such file or directory

I could start up playgound successfully, seems the mkdir failure error log doesn't affect the playground. this code https://github.com/apache/gravitino-playground/blob/main/init/hive/init.sh#L24-L26 is added by @jerqi , could you provide more context?

It should be used by rest service

gravitino.auxService.iceberg-rest.warehouse = hdfs://hive:9000/user/iceberg/warehouse/
