I think we already updated this in Spark 4. However for now you would have
to also include a JAR with the jakarta.* classes instead.
You are welcome to try Spark 4 now by building from master, but it's far
from release.

Pyspark follows SQL databases here. stddev is stddev_samp, and sample
standard deviation is the calculation with the Bessel correction, n-1 in
the denominator. stddev_pop is simply standard deviation, with n in the
denominator.

By marking it provided, you are not including this dependency with your
app. If it is also not somehow already provided by your spark cluster (this
is what it means), then yeah this is not anywhere on the class path at
runtime. Remove the provided scope.

In any event, have you tried updating Okio in the Spark build? I don't
believe you could just replace the JAR, as other libraries probably rely on
it and compiled against the current version.

Yeah, we generally don't respond to "look at the output of my static
analyzer".
Some of these are already addressed in a later version.
Some don't affect Spark.
Some are possibly an issue but hard to change without breaking lots of
things - they are really issues with upstream dependencies.
But
pp4 has one row, I'm guessing - containing an array of 10 images. You want
10 rows of 1 image each.
But, just don't do this. Pass the bytes of the image as an array,
along with width/height/channels, and reshape it on use. It's just easier.
That is how the Spark image representation works anyway

If it were exact matches, the best solution would be to load both datasets

For this case, I think your best bet is a UDF that contains the telephone

Yes more specifically, you can't ask for executors once the app starts,
in SparkConf like that. You set this when you launch it against a Spark

All else equal it is better to have the same resources in fewer executors.
More tasks are local to other tasks which helps perf. There is more
possibility of 'borrowing' extra mem and CPU in a task.

That's incorrect, it's spark.default.parallelism, but as the name suggests,

It's hard to evaluate without knowing what you're doing. Generally, using a
built-in function will be fastest. pandas UDFs can be faster than normal
UDFs if you can take advantage of processing multiple rows at once.

For Spark, the issue is maintaining simultaneous support for multiple Scala

versions.
Until Scala 2.12 support is reasonable to remove, it's hard to also support
Scala 3, as it would mean maintaining three versions of code.

I think it's fine to backport that to 3.3.x, regardless of whether it
clearly affects Spark or not.

This is sample variance, not population (i.e. divide by n-1, not n). I
think that's justified as the data are notionally a sample from a
population.

I don't think that can work. Your BroadcastUpdater is copied to the task,
with a reference to an initial broadcast. When that is later updated on the
driver, this does not affect the broadcast inside the copy in the tasks.

Wait, how do you start reduce tasks before maps are finished? is the idea
that some reduce tasks don't depend on all the maps, or at least you can
get started?
You can already execute unrelated DAGs in parallel of course.

Spark isn't a storage system or user management system; no there is no
notion of groups (groups for what?)

That just says a task failed - no real info there. YOu have to look at
Spark logs from the UI to see why.

Spark is built with and ships with a copy of Scala. It doesn't use your
local version.

It's important to realize that while pandas UDFs and pandas on Spark are
both related to pandas, they are not themselves directly related. The first
lets you use pandas within Spark, the second lets you use pandas on Spark.
Hard to say with this info but you want to look at whether you are doing
You have to provide your own Hadoop distro and all its dependencies. This
build is intended for use on a Hadoop cluster, really. If you're running
stand-alone, you should not be using it. Use a 'normal' distribution that
bundles Hadoop libs.

Spark does not use GPUs itself, but tasks you run on Spark can.
The only 'support' there is is for requesting GPUs as resources for tasks,
so it's just a question of resource management. That's in OSS.

Spark 3.3.0 supports 2.13, though you need to build it for 2.13. The
default binary distro uses 2.12.
