rdblue opened a new pull request #391: Fix create transaction metadata locations
URL: https://github.com/apache/incubator-iceberg/pull/391
 
 
   When a create transaction creates table metadata, it calls the underlying table operations to construct a location for the new metadata file. For metastore tables, that call fails because the base metadata for that table operations is null.
   
   This adds a method to get a temporary `TableOperations` instance that uses uncommitted table metadata. Transactions create temporary ops instances from intermediate metadata to ensure that the behavior of methods like `metadataFileLocation` and `locationProvider` use current table metadata instead of the base metadata, which may be null.
