This does not make sense to me.

The default value is 245 MB.

Conclusions should be supported by evidence.

The default value should be controlled by ZLO and should not be contained in the core-site file.

It is common for downstream projects to provide different default values ​​for certain configuration items when using a library. If you think the current default value should be changed, please provide benchmarks to support your idea.

The lzo's code is in a separate repository. I don't think we should maintain default values ​​related to lzo. It should be in hadoop-lzo repository not in hadoop.
