Description

Per ATM's suggestion in HADOOP-8598 for v2 let's make fs.trash.interval configured server side. If it is not configured server side then the client side configuration is used. The fs.trash.checkpoint.interval option is already server side as the emptier runs in the NameNode. Clients may manually run an emptier via hadoop org.apache.hadoop.fs.Trash but it's OK if it uses a separate interval.
