Walk over IntelliJ's "constant conditions and expressions" inspection results which are unrelated to null

IntelliJ's "Constant conditions and expressions" inspection mixes nullability-related problems and other types of problems. In Druid, there are 2500+ nullability related problems which makes the analysis impossible. [You can vote for this issue in YouTrack](https://youtrack.jetbrains.com/issue/IDEABKL-4141) to make it more likely that the problem is solved by IntelliJ developers.

For now, I [worked that around](https://youtrack.jetbrains.com/issue/IDEABKL-4141#focus=streamItem-27-3506899.0-0) and we can analyze actual bugs, 49 of them below.

Please go over the results below and fix the corresponding bugs.

Start by reviewing the IntelliJ findings in the listed Java files, beginning with AmbariMetricsEmitter.java, Parser.java, NumbersTest.java, and CombiningIteratorTest.java. Run the affected tests, including NumbersTest, CombiningIteratorTest, HdfsDataSegmentPusherTest, UtilsTest, and UtilsCompressionTest; done means the reported constant-condition problems are fixed and the relevant tests pass.
