            How to downgrade log.message.format.version in Kafka 2.5.0
            Asked 2021-Nov-16 at 22:25

            One of our Apache Kafka clusters has the following properties

            Yes, it should be possible to go to 2.2; it is not possible to go below 2.1




            Basic level linking leaflet to a database - recreating CoffeeShop example
            Asked 2021-Sep-07 at 08:42

            I am trying to work through the example from Chapter 5 of the Leaflet.js succinctly book - but cannot get any of the coffee shops to show on my map.

            Some of the commands give me errors so I've looked for workarounds, and I suspect the problem could be as simple as files not being in the correct place. Is there an idiot's guide to using databases with leaflet I could follow? Or can someone see the error I am making?

            My set up:

            • using XAMPP on a Mac - the MySQL Database and Apache Web Server are running
            • I created the leafletDB database using the terminal /Applications/xampp/xamppfiles/bin/mysql -u root -p create database leafletDB
            • I filled the database by copy paste into the terminal the contents of the CoffeeShops.sql file (I could not get the from CSV command mysql –uroot –pleaflet < "C:\CoffeeShops.sql"; to work, even changing the path to CoffeeShops.sql)
            • Checking the database using USE leafletDB; SHOW TABLES; and SELECT COUNT(*) FROM coffeeshops; all gave the expected results.
            • The leaflet database is located in /Applications/XAMPP/xamppfiles/var/mysql/
            • I copied the coffee.php file to the /Applications/XAMPP/xamppfiles/htdocs/CoffeeExample folder, which is the same file as the listing43.html file (the file that creates the map)
            • The only change I made to the listing43.html file was the path to the mugIcon (put in the same folder). I also tried simply removing the icon command - it made no difference.

            The map displays, any markers coded directly into the html file display - but nothing from the database.

            What have I got wrong?

            As requested here is a copy of all the code - sorry for how long this is

            I tried running this in an apache docker-container, and a mysql db in another docker-container. I got a couple of suggestions as to the possible errors. Although I believe suggestion 2-4 are the most likely to help you.

            1. The link you use for importing JQuery seems to be dated. Instead of:

            Because you're using two separate tables. You can put the second table into the first table and set .list to display: contents for desktop view.



            Randomly Split Dataframe into smaller chunks based on multiple (and similar) string conditions (rows can only used once)
            Asked 2021-Apr-19 at 10:05

            I have a data frame with 800 items (rows), and each row is located in a different area. The areas are: Allston, Boston, Brighton, Fenway, Brookline, Cambridge, Newton.

            Example Pandas Dataframe:



            Answered 2021-Apr-19 at 04:49

            Here's code for this specific case. I don't think it can be generalized much.

            The idea is from the areas that are allowed in group C, sample 0.1 * 800 = 80 of them and mark them as belonging to group C. Then from the unmarked rows that have areas allowed in group B, select 240 of them and mark them as belonging to group B. All the rest must be in group A.



            How to add a column to a dataframe and set all rows to a specific value
            Asked 2021-Feb-19 at 04:23


            After reading a large json file and capturing only the 'text' column, I would like to add a column to dataframe and set all rows to a specific value:



            Answered 2021-Feb-19 at 04:23

            The problem is that your read_json(....).text line returns a series, not a dataframe.

            Adding a .to_frame() and referencing the column in the following line should fix it:



            Incorrect element returned from list
            Asked 2020-Dec-09 at 19:57

            I am attempting to slice a list. When I iterate through the nested list one result has the correct elements corresponding to the index, the other result is one prior to the index number.



            Answered 2020-Dec-09 at 19:57

            You always append to loop2200using index1[0] and index1[1], but new indexes are being appended to index1: change these to index1[-2] and index1[-1] (i.e. using the last two indexes added to index1) and that will update loop2200 correctly.



            Setting kafka mirroring using Brooklin
            Asked 2020-Oct-14 at 11:49

            I am trying to test out Brooklin for mirroring data between kafka clusters. I am following the wiki

            Unlike the wiki - I am trying to setup the mirroring between 2 different clusters. I am able to start the Brooklin process and the Datastream but I cannot manage to mirror messages. Brooklin is running on the source kafka cluster ATM. I am trying to mirror topic 'test'

            The for brooklin is



            Answered 2020-Oct-14 at 11:49

            This was an issue on my end - I had a typo in the topic name configured for mirroring.



            How can I plot multiples columns with completely diffent meaning in same plot
            Asked 2020-Apr-26 at 01:37

            I have the follow data. How can I plot the three columns together (dist, price and count) for each neighbourhood?



            Answered 2020-Apr-26 at 01:37

            What you want is called a grouped barplot. You can melt the dataframe, which reformats your dataframe in a long format i.e. each neighbourhood and one variable at a time per row. Then apply the seaborns barplot to this melted dataframe.

            Update: since the y-values are far apart, we can add some labels. This is a workaround that goes through each row, and appends the label to the corresponding bar. The values you add to x and y are just by trial and error.
