The issue was with the Java SDK (or JDK) version. Currently pyspark only supports JDK versions 8 and 11 (the most recent one is 17) To download the legacy versions of JDK, head to https://www.oracle.com/br/java/technologies/javase/jdk11-archive-downloads.html and download the version 11 (note: you will need to provide a valid e-mail and password to create an Oracle account)

Here is a script in Python that is used to clone repositories given the github account name (source_account), the name of the source repo (source_repo), and the source branch (source_branch).

In your case (python program), you can use sigmavirus24/github3.py which give you access to a wrapper to GitHub CLI.

The gh repo fork command mentioned in the comments is available through their own API functions.

ANSWER

Answered 2021-Nov-24 at 15:26

Normally data files are located inside table location without subdirectories.

UNION ALL is being optimized (most probably you are using Tez) and each query is running in parallel, independently as separated mapper tasks. This requires separate subdirectories to be created for each query in UNION ALL to make it possible to write results of each query simultaneously, this is why you have two directories.

These settings allow Hive to read subdirectories:

QUESTION

Merging two Data frames with fuzzy merge/sqldf

Asked 2021-Nov-05 at 19:16

I have the following dataframes (df11 and df22) I'd like to do a merge/full join on with "UserID=UserID" and date difference <= 30 . So if the UserIDs match up AND the date's are less than or equal to 30, I'd like them merged into one singular row. I've looked at fuzzy join here and sqldf here but I can't figure out how to implement either of those for my data frames.

Answered 2021-Nov-05 at 17:59

One way is to first create "+/- 30 day" columns in one of them, then do a standard date-range join. Using sqldf:

The dataframe compares two companies per year. Like this:

For every c1 I want to look at c2 and delete rows which are in the previous year. I found a similar problem but with just one c. Here are some of my tries so far:
