Re: [announce] BeakerX supports Scala+Spark in Jupyter

In Jupyter, notebooks have just one kernel at a time so I am not aware of any conflicts. On Jun 7, 2018 9:09 PM, "Irving Duran" wrote: So would you recommend not to have Toree and BeakerX installed to avoid conflicts? Thank you, Irving Duran On 06/07/2018 07:55 PM, s...@draves.org wrote:

how to call database specific function when reading writing thru jdbc

For example, in SQL Server, when reading, I want to call a built-in function: STAsText() SELECT id, shape.STAsText() FROM SpatialTable val df = _sparkSession .read .jdbc(url, "dbo.SpatialTable", props) .select("shape.STAsText()") // No, this doesn't work.

Re: If there is timestamp type data in DF, Spark 2.3 toPandas is much slower than spark 2.2.

I haven't noticed or seen this behavior.  Have you noticed this with by testing the same dataset between versions? Thank you, Irving Duran On 06/06/2018 11:22 PM, 李斌松 wrote: > If there is timestamp type data in DF, Spark 2.3 toPandas is much > slower than spark 2.2. signature.asc

Re: [announce] BeakerX supports Scala+Spark in Jupyter

The %%spark magic comes with BeakerX's Scala kernel, not related to Toree. On Thu, Jun 7, 2018, 8:51 PM Stephen Boesch wrote: > Assuming that the spark 2.X kernel (e.g. toree) were chosen for a given > jupyter notebook and there is a Cell 3 that contains some Spark DataFrame > operations ..

Re: [announce] BeakerX supports Scala+Spark in Jupyter

Assuming that the spark 2.X kernel (e.g. toree) were chosen for a given jupyter notebook and there is a Cell 3 that contains some Spark DataFrame operations .. Then : - what is the relationship does the %%spark magic and the toree kernel? - how does the %%spark magic get applied to that

Re: Append In-Place to S3

I tried a different tactic. I still append based on the query below, but I add another deduping step afterwards, writing to a staging directory then overwriting back. Luckily, the data is small enough for this to happen fast. Cheers, Ben > On Jun 3, 2018, at 3:02 PM, Tayler Lawrence Jones >
