kainoa21 opened a new pull request #4183:
URL: https://github.com/apache/iceberg/pull/4183


   Implements the catalog Factory interface while also attempting to decouple 
catalog loading from requiring hadoop dependencies (see 
[#3117](https://github.com/apache/iceberg/issues/3117)).
   
   For now this attempts to leave all of the existing catalog creation 
interfaces in tact but swaps out `Configuration` for `Object` as a follow on 
the previous work in [#3590](https://github.com/apache/iceberg/pull/3590).  If 
we end up going this direction, some additional work will be necessary to 
ensure no loss of functionality for the existing Hadoop and Hive catalog 
implementations when using the new interface.
   
   While testing these changes locally, I was able to load a non-hadoop based 
catalog in a Flink SQL environment without any hadoop jars.  Though I did still 
eventually hit an error while attempting to read parquet files due to parquet's 
[hadoop 
dependency](https://github.com/apache/parquet-mr/blob/master/parquet-hadoop/src/main/java/org/apache/parquet/ParquetReadOptions.java#L174).
