Please review and fix typos in a whole batch of code, or don't bother and close this

I am fixing some codes around here - https://github.com/apache/spark/pull/19290/files#diff-d9f92e07db6424e2527a7f9d7caa9013R328. If this one is only the one, let me fold this into mine.

I have not found other typos and sorry i'm not agree with you. Since this spelling mistake affects the API doc in official website, we should fix it of course rather than 'don't bother and close this'. Thanks.

I don't think we should ever encourage to fix a single typo. It doesn't look making any harm to the context or contents really.

[HyukjinKwon]

I can give you many reasons - reviewing cost, build cost (including retriggering Jenkins build when failed unexpectedly, for example, -9 signal), potentially making conflicts / rebasing in other PRs, potentially swarming PRs and potentially inactive PRs that someone should ping (and should be manually closed by another PR). Do you really think it is worth fixing it over those minimal costs?

@cloud-fan @gatorsmile Could you please help to review this and merge it to master? Thanks.

@HyukjinKwon will make this change in another PR. We do need to push back on tiny PRs. It's a problem because some people are actually incentivized based on number of patches and it costs the project to accept that.

[zuotingbing]

if we find some mistakes likes this , shouldn't we to report it at first?

[HyukjinKwon]

I'd help review other PRs and leave a comment when someone fixes some codes around it rather than proposing it alone, or you can buffer it in your local and flush it.
