Nice reading. Can you give a comparison on Hive on MR3 and Hive on Tez?
Thanks

Just a question why there are so many SQL based tools existing for data

The ones I know,
Spark
Flink
Ignite
Impala
Drill
Hive
…
They are doing the similar jobs IMO.
Thanks
BTW , is MLlib still in active development?
Thanks

For online recommendation systems, continuous training is needed. :)
And we are a living video player, the content is changing every minute, so
a real time rec system is the must.

we are keeping the training with the input content from a streaming. But
the framework is tensorflow not spark.

Hello,
I have written a free book which is available online, giving a beginner
introduction to Scala and Spark development.

I am wondering why the list in scala spark can be converted into a
dataframe directly?

*df*: *org.apache.spark.sql.DataFrame* = [fruit: string]

You need to install scala first, the current version for spark is 2.12.15
I would suggest you install scala by sdk which works great.

You can treat it as a csf file and load it from spark:

What's the use of foreachRDD?

Don’t use Python RDD, using dataframe instead.

I did a comparison for pyspark RDD, scala RDD, pyspark dataframe and a pure

Hello
When spark started in my home server, I saw there were two ports open then.
8080 for master, 8081 for worker.
If I keep these two ports open without any network filter, does it have
security issues?

Using the dataframe API I need to implement a batch filter:
DF. select(..).where(col(..) != ‘a’ and col(..) != ‘b’ and …)
There are a lot of keywords should be filtered for the same column in where
statement.
How can I make it more smater? UDF or others?
Thanks & Happy new Year!
