Also, you need to squeeze your commits into one before we finally merge this request.

yeah, your pr is considered the situation that CHUNJUN_HOME is chunjun-dist, like

ls chunjun-dist           
bin                     connector               dirty-data-collector    formats                 metrics
chunjun-core-master.jar ddl                     docker-build            lib                     restore-plugins

which means that user use chunjun from release package.
But we also need to consider the situation that CHUNJUN_HOME is chunjun(project path, parent path of chunjun-dist), like

 ls chunjun
CONTRIBUTING.md                 chunjun-assembly                chunjun-dist                    chunjun-restore                 flinkx-core                     lib
LICENSE                         chunjun-clients                 chunjun-docker                  chunjun-sql                     flinkx-dirtydata-collectors     mvnw
README.md                       chunjun-connectors              chunjun-examples                chunjun.iml                     flinkx-docker                   mvnw.cmd
README_CH.md                    chunjun-core                    chunjun-formats                 docs_zh                         flinkx-formats                  pom.xml
bin                             chunjun-dev                     chunjun-local-test              flinkx-clients                  flinkx-metrics                  website
build                           chunjun-dirty                   chunjun-metrics                 flinkx-connectors               flinkx-restore

which means that user use chunjun from Git clone.
So you need to consider this two situations using 'if' statement.

[lvyanquan]

These two else case can be merged into one.

Look good to me.
