QUESTION
I'm trying to aggregate a spark dataframe up to a unique ID, selecting the first non-null value from that column for that ID given a sort column. Basically replicating MySQL's group_concat function.
The SO post here Spark SQL replacement for MySQL's GROUP_CONCAT aggregate function was very helpful in replicating the group_concat for a single column. I need to do this for a dynamic list of columns.
I would rather not have to copy this code for each column (dozen +, could be dynamic in the future), so am trying to implement in a loop (frowned on in spark I know!) given a list of column names. Loop runs successfully but, the previous iterations don't persist even when the intermediate df is cached/persisted (re: Cacheing and Loops in (Py)Spark).
Any help, pointers or a more elegant non-looping solution would be appreciated (not afraid to try a bit of scala if there is a functional programming approach more suitable)!
Given following df:
unique_id row_id first_name last_name middle_name score 1000000 1000002 Simmons Bonnie Darnell 88 1000000 1000006 Dowell Crawford Anne 87 1000000 1000007 NULL Eric Victor 89 1000000 1000000 Zachary Fields Narik 86 1000000 1000003 NULL NULL Warren 92 1000000 1000008 Paulette Ronald Irvin 85 ...ANSWER
Answered 2021-Dec-01 at 23:28I found a solution to my own question: Add a .collect()
call on my dataframe as I join to it, not a persist()
or cache()
; this will produce the expected dataframe.
QUESTION
I am trying to create a menu using @szhsin/react-menu
. I am getting an error that element
is undefined. componentDidMount
has not run yet (Nothing in the Console Log). I would have thought my if (this.state.Categories == null)
would catch before AddMenu
is ever called.
ANSWER
Answered 2021-Nov-16 at 21:29this.state.Categories is undefined not null. You should try if(!this.state.Categories) instead of if(this.state.Categories == null)

Answered 2020-Apr-30 at 21:36The XML structure is not the best. It is better to have a tag as a container for the team info, coaches, and players XML fragments.
