KAFKA-5929: Save pre-assignment to file to avoid too long text to display when do topic partition reassign When do partition reassign - before pr Pre-assignment will be printed directly. It is not friendly when the text is too long. - after pr Pre-assignment will still be printed directly, but will be save to a file at the same time, naming with suffix ".rollback" of "reassignment-json-file". For example: ``` ./kafka-reassign-partitions.sh --reassignment-json-file test.json ... ``` then we may get a file **test.json.rollback** You can merge this pull request into a Git repository by running: $ git pull https://github.com/uncleGen/kafka KAFKA-5929 Alternatively you can review and apply these changes as the patch at: https://github.com/apache/kafka/pull/3897.patch To close this pull request, make a commit to your master/trunk branch with (at least) the following in the commit message: This closes #3897 ---- commit b5806c9f09459e473d6d1eb66c46a546c526d9c7 Author: uncleGen <husty...@gmail.com> Date: 2017-09-19T07:40:09Z Save pre-assignment to file to avoid too long text to display when do topic partition reassign commit 19d3f84a237c3a685d805f0974282734fcc8e655 Author: uncleGen <husty...@gmail.com> Date: 2017-09-19T08:23:50Z findbugs fix ---- ---
