Description

https://github.com/cloudera/Impala/blob/cdh6.2.0/be/src/common/init.cc#L224-L228 just checks if there is a file configured or not. This results in startup failures for practically empty redaction rule files, like this one emitted by CM on an empty redaction rule configuration:

{
  "version": 1,
  "rules": []
}
