I worked with @zizhong on this pull request and it looks good to me.

Looks quite reasonable. I think we can improve the commit messages though. These guidelines are good advice.

This looks like it's solving/a duplicate of https://issues.apache.org/jira/browse/TS-2152

The code looks good to me too. If you're renaming commits per @jpeach's comments might want to reflect this & we can close out both issues.

Hi @ericcarlschwartz , if you're cool with he proposed patch I'll land this one and we can close out TS-2152 as a dupe.

[zwoop]

Yeah, close TS-2152 as a dupe of TS-3780, since there's so much work done on this PR already. In general, please file Jira's before work / pull requests are done, such that we avoid (minimize) risk of duplicated efforts / work.

Sounds good to me just wanted to make sure they both get closed out!
