Java SPI jar reload in Spark
I have a Spark Streaming application, which dynamically calling a jar (Java SPI), and the jar is called in a mapWithState() function, it was working fine for a long time.
Recently, I got a requirement which required to reload the jar during runtime.
But when the reloading is completed, the spark streaming job got failed, and I get the following exception, it seems the spark try to deserialize the checkpoint failed.
My question is whether the logic in the jar will be serialized into checkpoint, and is it possible to do the jar reloading during runtime in Spark Streaming?

Re: Java SPI jar reload in Spark
Posted by Ryan <ry...@gmail.com>.
I'd suggest scripts like js, groovy, etc.. To my understanding the service
loader mechanism isn't a good fit for runtime reloading.

Re: Java SPI jar reload in Spark
Posted by "Jonnas Li(Contractor)" <zh...@envisioncn.com>.
To be more explicit, I used mapwithState() in my application, just like this:
stream = KafkaUtils.createStream(..)
mappedStream = stream.mapPartitionToPair(..)
stateStream = mappedStream.mapwithState(MyUpdateFunc(..))
stateStream.foreachRDD(..)
I call the jar in MyUpdateFunc(), and the jar reloading is triggered by some other event.
I'm not sure if this approach is feasible. To my understand, Spark will checkpoint the status, so the application can’t be updated at runtime, that’s why I got the exception.
Any suggestion is welcome, if there is any other idea to do something like this, I just want to provide a approach to enable users can customize for their business logic.

主题: Re: Java SPI jar reload in Spark
I used java.util.ServiceLoader<S><https://docs.oracle.com/javase/7/docs/api/java/util/ServiceLoader.html> , as the javadoc says it supports reloading.
Please point it out if I'm mis-understanding.

Thank for your quick response.
These jars are used to define some customize business logic, and they can be treat as plug-ins in our business scenario. And the jars are developed/maintain by some third-party partners, this means there will be some version updating.
My expectation is update the business code with restarting the spark streaming job, any suggestion will be very grateful.

主题: Re: Java SPI jar reload in Spark
Why do you need jar reloading? What functionality is executed during jar reloading. Maybe there is another way to achieve the same without jar reloading. In fact, it might be dangerous from a functional point of view- functionality in jar changed and all your computation is wrong.

I have a Spark Streaming application, which dynamically calling a jar (Java SPI), and the jar is called in a mapWithState() function, it was working fine for a long time.
Recently, I got a requirement which required to reload the jar during runtime.
But when the reloading is completed, the spark streaming job got failed, and I get the following exception, it seems the spark try to deserialize the checkpoint failed.
My question is whether the logic in the jar will be serialized into checkpoint, and is it possible to do the jar reloading during runtime in Spark Streaming?

Re: Java SPI jar reload in Spark
Posted by "Jonnas Li(Contractor)" <zh...@envisioncn.com>.
I used java.util.ServiceLoader<S><https://docs.oracle.com/javase/7/docs/api/java/util/ServiceLoader.html> , as the javadoc says it supports reloading.
Please point it out if I'm mis-understanding.

Thank for your quick response.
These jars are used to define some customize business logic, and they can be treat as plug-ins in our business scenario. And the jars are developed/maintain by some third-party partners, this means there will be some version updating.
My expectation is update the business code with restarting the spark streaming job, any suggestion will be very grateful.

主题: Re: Java SPI jar reload in Spark
Why do you need jar reloading? What functionality is executed during jar reloading. Maybe there is another way to achieve the same without jar reloading. In fact, it might be dangerous from a functional point of view- functionality in jar changed and all your computation is wrong.

I have a Spark Streaming application, which dynamically calling a jar (Java SPI), and the jar is called in a mapWithState() function, it was working fine for a long time.
Recently, I got a requirement which required to reload the jar during runtime.
But when the reloading is completed, the spark streaming job got failed, and I get the following exception, it seems the spark try to deserialize the checkpoint failed.
My question is whether the logic in the jar will be serialized into checkpoint, and is it possible to do the jar reloading during runtime in Spark Streaming?

Re: Java SPI jar reload in Spark
Posted by "Jonnas Li(Contractor)" <zh...@envisioncn.com>.
Thank for your quick response.
These jars are used to define some customize business logic, and they can be treat as plug-ins in our business scenario. And the jars are developed/maintain by some third-party partners, this means there will be some version updating.
My expectation is update the business code with restarting the spark streaming job, any suggestion will be very grateful.

主题: Re: Java SPI jar reload in Spark
Why do you need jar reloading? What functionality is executed during jar reloading. Maybe there is another way to achieve the same without jar reloading. In fact, it might be dangerous from a functional point of view- functionality in jar changed and all your computation is wrong.

Recently, I got a requirement which required to reload the jar during runtime.
But when the reloading is completed, the spark streaming job got failed, and I get the following exception, it seems the spark try to deserialize the checkpoint failed.
My question is whether the logic in the jar will be serialized into checkpoint, and is it possible to do the jar reloading during runtime in Spark Streaming?

Re: Java SPI jar reload in Spark
Posted by Jörn Franke <jo...@gmail.com>.
Why do you need jar reloading? What functionality is executed during jar reloading. Maybe there is another way to achieve the same without jar reloading. In fact, it might be dangerous from a functional point of view- functionality in jar changed and all your computation is wrong.
