      Work Description: adoroszlai commented on pull request #135: HDDS-2451. Use lazy string evaluation in preconditions
URL: https://github.com/apache/hadoop-ozone/pull/135
 
 
   ## What changes were proposed in this pull request?
   
   Use the version of `Preconditions.check...` that accepts `errorMessageTemplate` and `errorMessageArgs`.
   
   There are occurrences of the `errorMessage` version left, but they do not seem to be important:
   
   1. use constant message, or
   2. are infrequently used (eg. one-time init in `MetadataKeyFilters`), or
   3. only append a plain `long` (container ID) to the message.

   ## How was this patch tested?
   
   Ran related unit tests and checkstyle.
