> Code Warning
> EC Call to
> org.apache.hadoop.hdfs.server.protocol.DatanodeRegistration.equals(org.apache.hadoop.hdfs.protocol.DatanodeInfo)
> in
> org.apache.hadoop.hdfs.server.datanode.BlockRecoveryWorker$RecoveryTaskContiguous.recover()
> Details
> EC_UNRELATED_TYPES: Call to equals() comparing different types
> This method calls equals(Object) on two references of different class types
> and analysis suggests they will be to objects of different classes at
> runtime. Further, examination of the equals methods that would be invoked
> suggest that either this call will always return false, or else the equals
> method is not be symmetric (which is a property required by the contract for
> equals in class Object).
