> I am trying to implement a recommender using Mahout. To create the DataModel
> I am using FileDataModel type. After creating the Recommender object , I want
> to save the model for later usage , just like what we have in Spark models.
> FileDataModel is implementing and inheriting Serializable classes , so this
> means that it can be Serialized. However when I try to write it the
> "java.io.NotSerializableException: com.google.common.base.Splitter" exception
> is thrown.
> The root cause of this exception is "private final Splitter
> delimiterPattern;" variable of FileDataModel class. It is a non-serializable
> third party class which is not marked as a transient field in the
> FileDataModel class, as a result of this we get the exception mentioned above.
> As a workaround , I created my own "MyFileDataModel" which is an exact copy
> of "FileDataModel" class but the "delimiterPattern" variable is marked as
> transient and it works perfectly. It would be better to mark the field as
> transient in the original class.
