…chema up-conversion in compaction Dear Gobblin maintainers, Please accept this PR. I understand that it will not be reviewed until I have checked off all the steps below! ### JIRA - [x] My PR addresses the following [Gobblin JIRA](https://issues.apache.org/jira/browse/GOBBLIN/) issues and references them in the PR title. For example, "[GOBBLIN-XXX] My Gobblin PR" - https://issues.apache.org/jira/browse/GOBBLIN-1257 ### Description - [x] Here are some details about my PR, including screenshots (if applicable): Currently, on schema change while copying map/list entries from the original schema into the evolved schema, all the entries in the collection point to the same reference. This is inadvertently caused by re-using the same WritableComparable object for all the values. In addition to fixing this issue, this PR: 1. Refactors/enhances existing unit tests, and 2. Introduces a new convenience class for local testing of the compaction job and provides a simple way of reproducing compaction issues locally. This class requires users to provide input data records in json format along with an input ORC schema. It generates the corresponding input ORC files and runs the compaction job against the generated input. ### Tests - [x] My PR adds the following unit tests __OR__ does not need testing for this extremely good reason: Added tests to OrcUtilsTest class. ### Commits - [x] My commits all reference JIRA issues in their subject lines, and I have squashed multiple commits if they address the same issue.
