Hello Xiao, there are multiple patches in Spark 3.2 depending on parquet
1.12, so it might be easier to wait for the fix in parquet community
instead of reverting all the related changes. The fix in parquet community
is very trivial, and we hope that it will not take too long. Thanks.

Since I can not find the commit of `Preparing development version

force-push. I'll follow Marcelo's suggestion to have another rc7 cut. Thus,

oh, I meant to say cdh5.1.3 used by Jakub's company is based on 2.3. You
can see it from the first part of the Cloudera's version number - "2.3.0-cdh
5.1.3".

Hi Xiangrui,
It seems that it's stateless so will be hard to implement
regularization path. Any suggestion to extend it? Thanks.

Okay, I got it. In Estimator, fit(dataset: SchemaRDD, paramMaps:
Array[ParamMap]): Seq[M] can be overwritten to implement
regularization path. Correct me if I'm wrong.

I'm working on LinearRegressionWithElasticNet using OWLQN now. This
will do the data standardization internally so it's transparent to
users. With OWLQN, you don't have to manually choose stepSize. Will
send out PR soon next week.

By default, depth 2 is used, so if you have so many partitions of
large vector, this may still cause issue. You can increase the depth
into higher numbers such that in the final reduce in driver, the
number of partitions are very small.

Hi Robin,
You can try this PR out. This has built-in features scaling, and has
ElasticNet regularization (L1/L2 mix). This implementation can stably
converge to model from R's glmnet package.

It's a bug in breeze's side. Once David fixes it and publishes it to
maven, we can upgrade to breeze 0.11.2. Please file a jira ticket for
this issue. thanks.

ataset to avoid the second cache. In this case,
the code will be more complicated, so I will split the code into two
paths. Will be done in another PR.

Hi Theodore,
I'm currently working on elastic-net regression in ML framework, and I
decided not to have any extra layer of abstraction for now but focus
on accuracy and performance. We may come out with proper solution
later. Any idea is welcome.

I thought LGPL is okay but GPL is not okay for Apache project.

Is your HDP implementation based on distributed gibbs sampling? Thanks.

Interesting. For feature sub-sampling, is it per-node or per-tree? Do
you think you can implement generic GBM and have it merged as part of
Spark codebase?

our current linear regression, but currently, there is no open source
implementation in Spark.

Hi YiZhi,
Sure. I think Holden already created a JIRA for this. Please
coordinate with Holden, and keep me in the loop. Thanks.
