Follow this checklist to help us incorporate your contribution quickly and easily:

[x] Make sure there is a Github issue filed for the change (usually before you start working on it). Trivial changes like typos do not require a Github issue. Your pull request should address just this issue, without pulling in other changes - one PR resolves one issue.
[x] Format the pull request title like [ISSUE #123] Fix UnknownException when host config not exist. Each commit in the pull request should have a meaningful subject line and body.
[x] Write a pull request description that is detailed enough to understand what the pull request does, how, and why.
[x] Write necessary unit-test to verify your logic correction, more mock a little better when cross module dependency exist.
[x] Run `mvn clean compile --batch-mode -DskipTests=false -Dcheckstyle.skip=false -Drat.skip=false -Dmaven.javadoc.skip=true to make sure basic checks pass.
