> During the execution of this script, the result of diff is "Only in" in
> Chinese, not "Only in" in English, and the script needs to match the English
> "Only in", so it fails to copy the old environment's hadoop_config directory
> successfully in this step. which is required to match the English "Only in"
> in the script, so the old environment's hadoop_conf cannot be copied
> successfully in this step.
> Upgrade scripts need to take into account that differences in the character
> set of the environment and other factors may result in commands not
> executing as expected.
