Using space() you can produce a string of spaces with lenght=sampling_rate-1 , split it and explode with lateral view, it will duplicate rows.

You need to add scala-compiler configuration to your pom.xml. The problem is without that there is nothing to compile your SparkTrans.scala file into java classes.

SQL: Extract from messy JSON nested field with backslashes

Asked 2021-Jun-11 at 21:04

I have a table that has some rows with normal JSON and some with escaped values in the JSON field (backslashes)

id obj 1 {"is_from_shopping_bag":true,"products":[{"price":{"amount":"18.00","currency":"USD","offset":100,"amount_with_offset":"1800"},"product_id":"1234","quantity":1}],"source":"cart"} 2 {"is_from_shopping_bag":"","products":"[{\ "product_id\ ":\ "2345\ ",\ "price\ ":{\ "currency\ ":\ "USD\ ",\ "amount\ ":\ "140.00\ ",\ "offset\ ":100},\ "quantity\ ":1}]"}

(Note: I needed to include a space after the backslashes in the above table so that they would show up in the github generated markdown table -- my actual table does not include those spaces between the backslash and the quote character)

Flutter dart export hive saved data to file to retrieve later

Asked 2021-Jun-09 at 18:46

I am developing a barcode app and save the data to hive. What I need to know is there a way to export the saved hive database to a backup file and be able to retrieve it for instance if the app crashed or your phone is lost. This is for blind accessibility. Want to export the data to a file that I can save to my pc to store and if something happens I do not have to scan all the products again to build the database. If hive can not do this can someone point me in a direction of which flutter dart database can do this. Thank you

There is not a "out-of-the-box" solution for that as far as I know. It depends a lot on your use case of how you want to do that (since there are many ways). For a complete example of how I did that for my app, you can take a look here: https://github.com/Kounex/obs_blade/blob/master/lib/views/settings/logs/log_detail/log_detail.dart (I made use of the share package in order to easily export it - but that's not necessary)

Flutter also has its own documentation on reading and writing files (https://flutter.dev/docs/cookbook/persistence/reading-writing-files) - I will add some information to round it up:

Storage location

First of all we have to think about where to store the "backup file". Flutter exposes common paths on its own which you can make use of (additionally the path_provider package gives you more flexibility). If you want this backup file to be temporarily, you can for example use:

Drop a hive table named "union"

Asked 2021-Jun-08 at 20:19

I am trying to drop a table names "union" but I keep getting an error. I am not sure who and how created that table, but nothing works on it, including describe or select. Using "hdfs dfs -ls" outside of hive, I can see that table exists and there is data in it, but cannot drop the table. I am assuming there may be a problem because the table is called "union" and the error I get is

"cannot recognize input near 'union'".

How can I drop the table?
