Hi guys,
I need help in implementing XG-Boost in PySpark.
As per the conversation in a popular thread regarding XGB goes, it is
available in Scala and Java versions but not Python. But, we've to
implement a pythonic distributed solution (on Spark) maybe using DMLC or
similar, to go ahead with XGB
We have created multiples spark jobs (as far JAR) and run it using
spark-submit in a nohup mode. Most of the jobs quits after a while. We tried
to harness the logs for failures but the only message that gave us some clue
was "18/05/07 18:31:38 INFO Worker: Executor app-20180507180436-0016/0

The example works for me, please check your environment and ensure you are
using Spark 2.3.0 where OneHotEncoderEstimator was introduced.

Hello,
Today I used SparkSession.read.format(“HBASETABLE”).options.(“zk”,”
zkaddress”).load() API to create a dataset from HBase data source and of
course I write code to extends BaseRelation and PrunedFilteredScan to
provide Logical plan for this HBase data source.

Hello,
I run a Spark cluster on YARN, and we have a bunch of client-mode applications
we use for interactive work. Whenever we start one of this, an application
master container is started.
My understanding is that this is mostly an empty shell, used to request further
containers or get status
How about Structured Streaming with Kafka? It is possible to operate through
window time. For more information, see here

Hello
That is good to hear, but are there exist some good practical (Python or Scala)
examples ? This would help a lot.
I tried to do that by Apache Flink (and its CEP) and it was not so piece cake.
Best, Esa

Hi,
are you sure Dataset has a method withColumns?

Hello Everyone,
I am performing clustering on a dataset using PySpark. To find the number of
clusters I performed clustering over a range of values (2,20) and found the
wsse (within-cluster sum of squares) values for each value of k. This where
I found something unusual. According to my understand
Hello Esa,
all the steps that you described can be performed with Spark. I don't know
about CEP, but Spark Streaming should be enough.
Best,

Hi Spark-users,
I am using pyspark on a yarn cluster. One of my spark application launch
failed. Only the driver container had started before it failed on the
ACCEPTED state. The error message is very short and I cannot make sense of
it. The error message is attached below. Any possible causes f
