How to union two dataframes which have same number of columns?

Asked 2022-Apr-11 at 22:02

Dataframe df1 contains columns : a, b, c, d, e (Empty dataframe)

Dataframe df2 contains columns : b, c, d, e, _c4 (Contains Data)

I want to do a union on these two dataframes. I tried using

unionByName exists since spark 2.3 but the allowMissingColumns only appeared in spark 3.1, hence the error you obtain in 2.4.

In spark 2.4, you could try to implement the same behavior yourself. That is, transforming df2 so that it contains all the columns from df1. If a column is not in df2, we can set it to null. In scala, you could do it this way:

There is a Spark JIRA "Any depth search not working in get_json_object ($..foo)" open for full JsonPath support.

Until it is resolved, I'm afraid creating a UDF that uses a "general-purpose" JsonPath implementation might be the one and only option:

Problems when writing parquet with timestamps prior to 1900 in AWS Glue 3.0

Asked 2022-Feb-10 at 13:45

Answered 2022-Feb-10 at 13:45

I made it work by setting --conf to spark.sql.legacy.parquet.int96RebaseModeInRead=CORRECTED --conf spark.sql.legacy.parquet.int96RebaseModeInWrite=CORRECTED --conf spark.sql.legacy.parquet.datetimeRebaseModeInRead=CORRECTED --conf spark.sql.legacy.parquet.datetimeRebaseModeInWrite=CORRECTED.

This is a workaround though and Glue Dev team is working on a fix, although there is no ETA.

Also this is still very buggy. You can not call .show() on a DynamicFrame for example, you need to call it on a DataFrame. Also all my jobs failed where I call data_frame.rdd.isEmpty(), don't ask me why.

Update 24.11.2021: I reached out to the Glue Dev Team and they told me that this is the intended way of fixing it. There is a workaround that can be done inside of the script though:

Explode map, then you can filter keys using LIKE. If you want to get single row per id_test, number even if there are many keys satisfying LIKE condition, use GROUP BY or DISTINCT.

Hive queries taking so long

Asked 2022-Jan-29 at 17:16

I have a CDP environment running Hive, for some reason some queries run pretty quickly and others are taking even more than 5 minutes to run, even a regular select current_timestamp or things like that. I see that my cluster usage is pretty low so I don't understand why this is happening.

How can I use my cluster fully? I read some posts in the cloudera website, but they are not helping a lot, after all the tuning all the things are the same.

Something to note is that I have the following message in the hive logs:

DROP TABLE & CREATE TABLE work with entries in the Metastore that is some kind of database that keeps the metadata about databases and tables. There could be the situation when entries in metastore don't exist so DROP TABLE IF EXISTS doesn't do anything. But when CREATE TABLE is executed, then it additionally check for location on DBFS, and fails if directory exists (maybe with data). This directory could be left from some previous experiments, when data were written without using the metastore.
