Description

FileSystem#getDelegationToken is incompatible with a multi-token fs like viewfs. FileSystem#addDelegationTokens is being added in HADOOP-7967 to call getDelegationToken on each of the fs mounts. The visibility of getDelegationToken must be reduced to protected since it's completely incompatible with a multi-token fs.
