Hi Minudika,
To add to what Oscar said, this blog post [1] should clarify it for you.
And this should be posted in the user-list not the dev.

To committers and contributors active in MLlib,
Thanks everyone who has started helping with the QA tasks in SPARK-18316!
I'd like to request that we stop committing non-critical changes to MLlib,
including the Python and R APIs, since still-changing public APIs make it
hard to QA. We need have a
I'm also curious about this. Is there something we can do to help
troubleshoot these leaks and file useful bug reports?

I see. I think I read the documentation a little bit too quick :)
My apologies.

It's a degenerate case of course. 0, 0.5 and 1 all make about as much
sense. Is there a strong convention elsewhere to use 0?
Min/max scaling is the wrong thing to do for a data set like this anyway.
What you probably intend to do is scale each image so that its max

Hi all,
I observed some weird behaviour while applying some feature transformations
using MinMaxScaler. More specifically, I was wondering if this behaviour is
intended and makes sense? Especially because I explicitly defined min and max.
Basically, I am preprocessing the MNIST dataset, and the
It's unlikely that you're hitting this, unless you have several tasks
writing at once on the same executor. Parquet does have high memory
consumption, so the most likely explanation is either that you're close to
the memory limit for other reasons, or that you need to increase the amount
of overhea
Thanks Ryan. I am running into this rarer issue. For now, I have moved away
from parquet but if I will create a bug in jira if I am able to produce
code that easily reproduces this.
Thanks,

Aniket,
The solution was to add a sort so that only one file is written at a time,
which minimizes the memory footprint of columnar formats like Parquet.
That's been released for quite a while, so memory issues caused by Parquet
are more rare now. If you're using Parquet default settings and a rec
In commonly used RDBM systems relations have no fixed order and physical
location of the records can change during routine maintenance
operations. Unless you explicitly order data during retrieval order you
see is incidental and not guaranteed.
Conclusion: order of inserts just doesn't matter.

Hi,
Say, I have a table with 1 column and 1000 rows. I want to save the result
in a RDBMS table using the jdbc relation provider. So I run the following
query,
"insert into table table2 select value, count(*) from table1 group by value
order by value"
While debugging, I found that the resultant
13 matches
