The serving layer holds on to data until a certain amount has been written, and then uploads it to HDFS. It will try to upload, however, if the process quits and there is still some data not uploaded to HDFS. You can configure the number of writes to be lower and thus upload more frequently (but perhaps creating more, smaller files). The serving layer is just saying that it does not yet see any model from the computation layer. That's probably true since the computation layer hasn't gotten data yet.

If you're using yarn-client, you're actually using YARN and not the Spark service that you see in CM. The Spark service is for standalone mode. I don't think that explains it per se, just an FYI. If the symptom is that the Hadoop jars are not being found in the classpath, maybe spot-check the locations it names in the classpath to see that they exist on the cluster? I wonder if one of them has some bad state of parcel directory. It's a long shot but would be my next guess.

Not that it's terribly helpful, but I tried the same on a CDH 5.1.3 cluster and it seemed to work fine. The error indicates some problem finding Hadoop classes. Do you have any modifications to the Spark config? or anything else changing the installation and so on? are you running the binaries from CDH or your own build?

Have a look at the parent packaging pom to see some additional settings like this that affect the CDH packaging. I don't know how much they're documented beyond this as it's generally rare for anyone to try to rebuild the source. Still, it ought not be hard.

Ah, add "-Dhadoop.profile=23" to the build line. Does that work?

Oh right, OK. Is Maven able to download the depenendencies? you don't see earlier errors?

This looks like errors in the modifications you made. This string is not in the original source code for instance: packagejavax.servlet不存在

I mean that it's internal to the service, not exposed as an endpoint. Although that wouldn't be hard. Let me put it on my radar as a feature request.

Hm, no, there isn't, but the data structure exists (unless disabled). If there's a reasonable use case for it this could be added as an endpoint.

Your signature is just a little bit off. The result of a join is not a triple, but a tuple whose second element is a tuple. You have: (_, (_, _),(_,_,device)) but I think you need: (_, ((_, _),(_,_,device)))
