[GitHub] spark pull request #21542: [WIP][SPARK-24529][Build] Add spotbugs into maven...

GitHub user kiszk opened a pull request:

    [WIP][SPARK-24529][Build] Add spotbugs into maven build process

    ## What changes were proposed in this pull request?
    
    This PR enables a Java bytecode check tool [spotbugs](https://spotbugs.github.io/) to avoid possible integer overflow at multiplication. When a problem is detected, the build process is stopped.
    Due to the tool limitation, some other checks will be enabled.
    
    This check is enabled at `compile phase. Thus, `mvn compile` or `mvn package` launches this check.
    
    ## How was this patch tested?
    
    Existing UTs

You can merge this pull request into a Git repository by running:

    [It](http://spotbugs.readthedocs.io/en/latest/bugDescriptions.html#im-check-for-oddness-that-won-t-work-for-negative-numbers-im-bad-check-for-odd) means `x % 2 == ` does not work correctly if x is negative.
    
    In this case, we know `value.length` is always non-negative . The current SpotBugs cannot detect this pre-condition. I cannot find to disable only this check in `findPuzzles`, too.
    
    Therefore, this is a workaround to avoid the false positive violation.

    @HyukjinKwon Thank you for your kindly look. Both fork and non-fork versions work well in my local environment. I am thinking about available memory size.

    Are we sure this Comparator never returns Int.MinValue? If it can, then this is still a legitimate possible bug.

    Does the spotbugs 3.1.3 plugin not already have this dependency? I would have assumed that's the default and we don't want to manage it separately. If we do maybe make a property for this version to make sure it doesn't vary?
