A follow up change of #22348
example is not up to date and we can not bring up the cluster due to missing configmap. Autoscaler is able to convert CR to autoscaler config so we don't need configmap anymore.
I recently realized that during a runtime_env creation process, a plugin/manager that is very slow to setup may block the creation of other runtime_env, so I make plugin/manager setup run in threads.
[The refactor of `PipManager`](https://github.com/ray-project/ray/pull/22381) is about to be completed, so I ignore it in this PR.
Combine `ParsedRuntimeEnv` and `RuntimeEnv` into `ray.runtime.RuntimeEnv`, details: #21495
- The `new RuntimeEnv` includes all external interfaces of `ParsedRuntimeEnv` and `old RuntimeEnv`.
- The `new RuntimeEnv` will be exposed directly to the user.
- example:
```python
runtime_env = ray.runtime_env.RuntimeEnv(working_dir="s3://workding_dir.zip",
pip=["requests"],
java_jars=["s3://jar1.zip"],
java_jvm_options=["-Dxxx=xxx"])
```
This PR supports setting actor level env vars for Java worker in runtime env.
General API looks like:
```java
RuntimeEnv runtimeEnv = new RuntimeEnv.Builder()
.addEnvVar("KEY1", "A")
.addEnvVar("KEY2", "B")
.addEnvVar("KEY1", "C") // This overwrites "KEY1" to "C"
.build();
ActorHandle<A> actor1 = Ray.actor(A::new).setRuntimeEnv(runtimeEnv).remote();
```
If `num-java-workers-per-process` > 1, it will never reuse the worker process except they have the same runtime envs.

To hidden symbols of thirdparty library, this pull request reuses internal namespace that can be imported by any external native projects without side effects.
Besides, we suggest all of contributors to make sure it'd better use thirdparty library in ray scopes/namspaces and only ray::internal should be exported.

In Envs with K8S and enabled SELinux there is a bug:
"/proc/nvidia/" is not allowed to mount in container
So, i made a rework for GPU detection based on GPutil package.

- Moved all `Deployment` instance creation to `DeploymentNode` level with only relevant info passed into it from `generate.py`. This abstraction makes more sense and less leaky.
- In `DeploymentNode`, we leverage ray core DAG's `_PyObjScanner` to find and replace only Deployment nodes init args & kwargs to deployment handle, which is only specific to `Deployment` instance, but not `DeploymentNode` itself. However this is the simplest and most robust way to handle nested args at `DAGNode` level.
- This implementation lives in ray core DAGNode level so we don't need to expose `_PyObjScanner` directly.
- Added serve pipeline tests to BUILD CI.
Whenever we spill, we try to spill all spillable objects. We also try to fuse small objects together to reduce total IOPS. If there aren't enough objects in the object store to meet the fusion threshold, we spill the objects anyway to avoid liveness issues.
However, the current logic always spills once we reach the end of the spillable objects or once we've reached the fusion threshold. This can produce lots of unfused objects if they are created concurrently with the spill.
This PR changes the spill logic: once we reach the end of the spillable objects, if the last batch of spilled objects is under the fusion threshold, we'll only spill it if we don't have other spills pending too. This gives the pending spills time to finish, and then we can re-evaluate whether it's necessary to spill the remaining objects. Liveness is also preserved.
`test_job_submission` has become [flakey](https://flakey-tests.ray.io/) due to timeout. This change increases the timeout in `test_failed_job_status` from 10 to 25 seconds.
Currently object transfers assume that the object size is fixed. This is a bad assumption during failures, especially with lineage reconstruction enabled and tasks with nondeterministic outputs.
This PR cleans up the handling and hopefully guards against two cases where the object size may change during a transfer:
1. The object manager's size information does not match the object in the local plasma store (due to async notifications). --> the object manager overwrites its own information if it finds that the physical object has a different size.
2. The receiver's created buffer size does not match the sender's object size. --> the receiver destroys the previous buffer and creates a new buffer with the correct size. This might cause some transient errors but eventually object transfer should succeed.
Unfortunately I couldn't trigger this from Python because it depends on some pretty specific timing conditions. However, I did add some unit tests for case 2 (this is the majority of the PR).
This PR fixes initializations artifacts related to the load metric summary and autoscaler summary.
Load metrics summaries are defined to be Falsey if the autoscaler has never received a resource message from the GCS.
We skip most autoscaler actions if load metrics is Falsey, because it doesn't makes sense to autoscale without load metrics. This also allows us to execute the TODO here: #22348 (comment) and remove the time.wait().
As for the autoscaler summary, it is possible for autoscaler.summary() to error outside of an autoscaler update in this scenario:
The very first call to NodeProvider.non_terminated_nodes fails, self.non_terminated_nodes remains a None object, and autoscaler.summary() fails trying to get an attribute of this None object.
The result is a confusing error message, as in #22515. This PR fixes that.
Closes#22515
- Added backbone of ray dag -> serve dag transformation and deployment extraction.
- Added util functions for deployment unique name generation .. ray_actor_options, replacement of DeploymentNode with deployment handle, etc.
Soft restarts don't work for tensorflow since there is still some leftover communication state in the actors which may lead to undefined behavior, such as causing training to hang.
Instead, this PR changes the failure handling for tensorflow to match torch and horovod, and recreates all the workers in case of failure. Also adds a test to check if fault tolerance works correctly for an actual tensorflow example. When testing locally, the test failed before the change, but passes after.
This change adds the GET, PUT, and DELETE commands for Serve’s REST API. The dashboard receives these commands and issues corresponding requests to the Serve controller.
When get a bunch of data from redis, we first initialize local variables and then put them in vector, which bring so much copies from stack to heap or from local variables to vector.
This tiny little change would save the copies.
This PR **enables the usage stats only on the release test infrastructure** (large scale tests Ray runs on a daily basis in a private infra). Note it is still disabled by default in Ray.
