            How to decode dictionary column when using pyarrow to read parquet files?
            Asked 2021-Jun-15 at 13:59

            I have three .snappy.parquet files stored in an s3 bucket, I tried to use pandas.read_parquet() but it only work when I specify one single parquet file, e.g: df = pandas.read_parquet("s3://bucketname/xxx.snappy.parquet"), but if I don't specify the filename df = pandas.read_parquet("s3://bucketname"), this won't work and it gave me error: Seek before start of file.

            I did a lot of reading, then I found this page

            it suggests that we can use pyarrow to read multiple parquet files, so here's what I tried:

            Guzzle/Nexmo Issues After Upgrading to Laravel 8
            Asked 2021-Jun-09 at 23:48

            I recently performed a rather large update to this web app, and for the most part it went off without a hitch... Until the app tries to send an SMS notification from staging/production.

            The upgrade from laravel 7.x to 8.x was quite simple and straightforward. At the same time we also installed Laravel Horizon. Everything went according to plan, and all works fine locally.

            When we deploy to staging/production however, queued SMS notifications fail with the following exception:

            ReflectionException: Class Http\Adapter\Guzzle6\Client does not exist in /home/forge/dev.example.com/releases/20210609194554/vendor/laravel/framework/src/Illuminate/Container/Container.php:836

            Looking in the stack trace we can see that Nexmo is the culprit:

            #5 /home/forge/dev.example.com/releases/20210609194554/vendor/nexmo/laravel/src/NexmoServiceProvider.php(150): Illuminate\Foundation\Application->make()

            However in our composer.json file we are requiring Guzzle 7 with the following:

            "guzzlehttp/guzzle": "^7.3",

            It is worth mentioning again at this point, I have no issues sending SMS locally, the main difference between local and staging environments is that locally I use Laravel Valet and Staging uses Laravel Envoyer.

            What I've tried so far:

            • Changing "guzzlehttp/guzzle": "^7.3" to "guzzlehttp/guzzle": "^6.5|^7.3"
            • Running php artisan horizon:purge and php artisan horizon:terminate both manually and in a deployment hook.
            • Restarting the laravel horizon daemon on forge.
            • trying php artisan queue:restart
            • running composer dump-autoload and composer dump-autoload -o
            • deleting composer.lock and the vendor/ directory from current/ then running composer install
            • Restarting PHP, Nginx, and eventually the entire server :(

            and more...

            Any help is greatly appreciated

            I see that the NexmoServiceProvider is trying to use the defined http_client in the config, so can you share what the .env has for NEXMO_HTTP_CLIENT ? I am pretty sure you have something wrong there or even not defined.

            And this is what it is defined in the config/nexmo.php related to that config:

            There are a couple of issues to address. The dockerfile as you have it will download a base golang ARM image, and try to use that to build. That's fine, as long as the required libs "know how" to build with an arm architecture. If they don't know how to build under arm (as seems to be the case here), you may want to try building under an AMD image of golang.

            Intel / AMD containers will run under ARM docker on an M1. There are a few ways to build AMD containers on an M1. You can use buildkit, and then: docker buildx build --platform linux/amd64 . or, you can add the arch to the source image by modifying the Dockerfile to include something like:

            Need Help in Rigidbody based FPS Controller in Unity
            Asked 2021-May-16 at 20:00

            I am Learning unity and trying to create a fps game, but while making its controller i am facing a bit problem, like i want to move player ,, but using rigidbody not the character controller as i want it to completely interact the environment, but when i try to make player move using addforce it works fine but when i stop pressing the moving keys even the player moves for some amount of time, i want a little more snappy movement, should i use addForce or should i move player by using velocity, and can you help me find the counter movement when i stop pressing the movement buttons, using the script not by increasing the friction

            ANSWER

            Answered 2021-May-16 at 20:00

            When you add force to a Rigidbody to move it you have a couple options on how to slow down that rigidbody.

            1. Consider setting the velocity to zero to stop movement instantly
            2. Consider Clamping the velocity of the GameObject
            3. Consider adding additional velocity in the opposite direction the rigid body is traveling.

            Apache Oozie throws ClassNotFoundException (org.apache.hadoop.conf.Configuration) during startup
            Asked 2021-May-09 at 23:25

            I built the Apache Oozie 5.2.1 from the source code in my MacOS and currently having trouble running it. The ClassNotFoundException indicates a missing class org.apache.hadoop.conf.Configuration but it is available in both libext/ and the Hadoop file system.

            I followed the 1st approach given here to copy Hadoop libraries to Oozie binary distro. https://oozie.apache.org/docs/5.2.1/DG_QuickStart.html

            I downloaded Hadoop 2.6.0 distro and copied all the jars to libext before running Oozie in addition to other configs, etc as specified in the following blog.

            https://www.trytechstuff.com/how-to-setup-apache-hadoop-2-6-0-version-single-node-on-ubuntu-mac/

            This is how I installed Hadoop in MacOS. Hadoop 2.6.0 is working fine. http://zhongyaonan.com/hadoop-tutorial/setting-up-hadoop-2-6-on-mac-osx-yosemite.html

            This looks pretty basic issue but could not find why the jar/class in libext is not loaded.

            • OS: MacOS 10.14.6 (Mojave)
            • JAVA: 1.8.0_191
            • Hadoop: 2.6.0 (running in the Mac)

            Answered 2021-May-09 at 23:25

            I was able to sort the above issue and few other ClassNotFoundException by copying the following jar files from extlib to lib. Both folder are in oozie_install/oozie-5.2.1.

            • libext/hadoop-common-2.6.0.jar
            • libext/commons-configuration-1.6.jar
            • libext/hadoop-mapreduce-client-core-2.6.0.jar
            • libext/hadoop-hdfs-2.6.0.jar

            While I am not sure how many more jars need to be moved from libext to lib while I try to run an example workflow/job in oozie. This fix brought up Oozie web site at http://localhost:11000/oozie/

            I am also not sure why Oozie doesn't load the libraries in the libext/ folder.
