   Looks like this might be causing this issue (Might be wrong here) : 
   we pass the conf we have HadoopFileIO to HadoopOutputFile : 
   
   https://github.com/apache/iceberg/blob/ea8bbe749753e3d1ddc595ce75a88a55a442a67e/core/src/main/java/org/apache/iceberg/hadoop/HadoopFileIO.java#L63-L65
   
   which is modified for ORC write path : 
   
   https://github.com/apache/iceberg/blob/ea8bbe749753e3d1ddc595ce75a88a55a442a67e/orc/src/main/java/org/apache/iceberg/orc/ORC.java#L165-L174
   
   
   Looks like it fails for ORC only : 
   > org.apache.iceberg.spark.extensions.TestCopyOnWriteMerge > testMergeWithSnapshotIsolation[catalogName = testhive, implementation = org.apache.iceberg.spark.SparkCatalog, config = {type=hive, default-namespace=default}, format = orc, vectorized = true, distributionMode = none] FAILED
   
   should we create new conf always and copy the existing hadoop confs in to new conf to avoid this ?
