Hi Jacek,
Thank you for responding back,
i have tried memory sink, and below is what i did
val fetchValue =
debeziumRecords.selectExpr("value").withColumn("tableName",
functions.get_json_object($"value".cast(StringType), "$.schema.name"))
.withColumn("operation",
functions.get_json_object($
Hi, all,
I want to include Sentry 2.0.0 in my Spark project. However it bundles
Hive 2.3.2. I find the newest Spark 2.2.1 still bundles old Hive jars,
for example, hive-exec-1.2.1.spark2.jar. Why does it upgrade to the new
Hive? Are they compatible?

Qin An.
Hi,
I want to load a spark dataframe column into T-Digest using java to
calculate quantile values. I write this code to do this, but it's giving
zero for size of tdigest. values are not added to tDigest.

Thank you.

Hi,
What about memory sink? That could work.

Hi,
Not that I'm aware of, but in your case checking out whether a JSON message
fit your schema and the pipeline would've taken pyspark alone with JSONs on
disk, wouldn't it?

Hi All,
I would like to infer JSON schema from a sample of data that i receive
from, Kafka Streams(specific topic), and i have to infer the schema as i am
going to receive random JSON string with different schema for each topic,
so i chose to go ahead with below steps,
a. readStream from Kafka(la
I found the root cause! There was mismatch between the StructField type and
the json message.
Is there a good write up / wiki out there that describes how to debug spark
jobs?
Thanks

I did what you said and I was finally able to update the scheme. But you're
right, it's very dirty, I have to modify almost all the scripts.
The problem of the scripts comes from having already a previous table in
that version, many of the tables or columns that I try to add, already exist
and it g
Hi,
Good try. As you can see, when you run upgrade using schematool, there is a
duplicate column error. Can you please look the script generated and edit
to avoid duplicate column?
Not sure why the Hive guys made it complicated, I did face same issues like
you.
Can anyone else give a clean and b
Hello Sandeep,
you can pass Row to UDAF. Just provide a proper inputSchema to your UDAF.
Check out this example https://docs.databricks.com/

I have tried what you propose, added the property to hive-site.xml, and
although with this option I can run hive, this does not solve my problem.
I'm sorry if maybe you explain me wrongly.
I need to save a dataframe transformed into spark in hive, with the version
of scheme 2.1.1 of hive (last sta
Thanks Georg. I have looked at UADF based on your suggestion. Looks like
you can only pass single column to UADF. Is there any way you can pass
entire Row to aggregate function?
I want to list of user defined function and given row object. Perform the
aggregation and return aggregated Row object.
Some code would help to debug the issue
