Description

It may be that trying to use distcp -p with S3a triggers a stack trace

java.lang.UnsupportedOperationException: S3AFileSystem doesn't support getXAttrs 
at org.apache.hadoop.fs.FileSystem.getXAttrs(FileSystem.java:2559) 
at org.apache.hadoop.tools.util.DistCpUtils.toCopyListingFileStatus(DistCpUtils.java:322)

Add a test to AbstractContractDistCpTest to verify that this is handled better. What is "handle better" here? Either ignore the option or fail with "don't do that" text
