I encountered the same problem and error when I wanted to inject constructor parameters in the Workmanager with the Dagger-Hilt. Follow these steps to inject constructor parameters in the Workmanager with Hilt:

Step 1: Remove the default initializer from the AndroidManifest.xml:

So why should they be notified of the reexecution immediately? I think it's unnecessary for some reducers who have read the data they want from worker A

The thing is reducers do not know that they already read all the data from mapper they want because mapper has failed and did not finish writing data.

Reducers has started reading data early before mapper completed and read some partial data. Mapper could produce more data if not failed.

Mapper has produced partial result files, then failed and new attempt has started.

Typically mappers and reducers are single-threaded and deterministic, this allows restarts and speculative execution. Suppose you do not use some non-deterministic functions like rand(), multi-threading in mapper (custom non-deterministic mapper). Also network/shuffle adds non-determinism. Mapper with multi core/multi threading can produce differently ordered output after restart. Mappers can use output of another mappers and even reducers (for example map-side join in modern implementations). The whole result should be deterministic to make it possible to restart but the order may not, it can be differently grouped files and number of files.

If reducer is commutative and also deterministic (typically yes), you can restart it and get the same result, if it is commutative, no problem with order of rows.

But is it possible to use partial results from one mapper instance (failed) and partial results from another one (new attempt), like read files 0000 - 0004 fron Map1_attempt1 and files 0005 - 0006 from Map1_attempt2 ? Only if mapper produces exactly the same number of files with the same order always. You see, if the whole result of Mapper should be deterministic, partial result may not. It depends on implementation.

Sending plain functions over the network will not work because of the language design. In a single program you can pass functions as arguments because they are compiled in the same binary. In the server process you can fetch their address/reference since they are mapped in memory but when you send the function you actually send the pointer to it which is not a valid address in the client's memory (hence the invalid pointer error).

To solve your problem I would go for the client registering a set of available functions with a server based on an id (could be a string mentioning the function name). The server will send back the function id in the Run RPC call and the client will select the function based on this id and run it

There are also some experimental libraries that can evaluate Go code at runtime but I would not consider them safe. This is one example.

Semantics of PureScript as such is pure and pretty much incompatible with this sort of thing. Same expression always produces same result. The results can be represented differently at a lower level, but in the language semantics they're the same.

And this is a feature, not a bug. In my experience, more often than not, a requirement like yours is an indication of a flawed design somewhere upstream.

An exception to this rule is FFI: if you have to interact with the underlying platform, there is no choice but to play by that platform's rules. One example I can give is React, which uses the JavaScript's implicit object identity as a way to tell components apart.

So the bottom line is: I urge you to reconsider the requirement. Chances are, you don't really need it. And even if you do, manually specified strings might actually be better than automatically generated ones, because they may help you troubleshoot later.

But if you really insist on doing it this way, good news: you can cheat! :-)

You can generate your IDs effectfully and then wrap them in unsafePerformEffect to make it look pure to the compiler. For example:

It seems because details is an array you can't just target each item's wage by "$details.wage" you would probably need to unwind (see the example usage) the array which will produce multiple entries that will have a details object where you can use details.wage

Maybe a simpler solution would be to use reduce to aggregate a total:

Let's suppose that Foo and Bar both implement INeedAction, and Foo has a property of type Bar.

Then a MyWorkerClass represents a work that is able to DoWork on a Foo. So far so good. However, look what happens when DoWork is called and it finds the Bar property. Since Bar implements INeedAction, you call

Yes, you need to copy-paste your program definition to separate supervisor processes.

And about the folder. You should use the /etc/supervisor/conf.d/. Just create the config file with SOMETHING-LIKE-A-PROJECT-NAME.conf and put your program definition into it.

And then check that your /etc/supervisord.conf contains the include section:

This is only possible if you are using NodePort type service. It's because by design the NodePort is opened on all nodes in the cluster including master nodes.

From the docs

NodePort: Exposes the Service on each Node's IP at a static port (the NodePort). A ClusterIP Service, to which the NodePort Service routes, is automatically created. You'll be able to contact the NodePort Service, from outside the cluster, by requesting :

If you are looking for a way to avoid this use ingress with ClusterIP type service.

It is clear in documentation that Django collectstatic looks only for files in folders that are set in
