// Wraps around all types of Alluxio journal entries.
//
// NOTE: Exactly one of the *Entry entries is expected to be set. Ideally we would use the 'oneof'
// protobuf syntax to enforce this. However, 'oneof' is only available since protobuf version
// 2.6.0 and adding this depedency would conflict with the version of protobuf used by Hadoop 2.x
// and Spark. We use protobuf version 2.5.0 instead, which is compatible with Hadoop and Spark.
