master-slave

问题 I have a Jenkins multi-configuration project that I want to build on two slaves (Slave-1 and Slave-2) which are located on two different VM's. I am having a problem with how Jenkins attempts to create different workspaces for each slave. I want to use the same workspace path on each VM. I am getting my project files from Perforce and want to put them in the directory c:\workspace on both VM's. However when I run a build, I look on the VM that has Slave-1 and it stores the project files under:

问题 Help me to chouse a simple (lightweight) solution to the master-slave replication of one table between two Postgresql databases. The table contains a large object. 回答1: Here you'll find a very good overview of the replication tools for PostgreSQL. Please, take a look and hopefully you'll be able to pick one.

问题 I am trying to run a basic script on spark cluster that takes in a file, converts it and outputs in different format. The spark cluster at the moment consists of 1 master and 1 slave both running on the same node. The full command is: nohup spark-submit --master spark://tr-nodedev1:7077 --verbose --conf spark.driver.port=40065 --driver-memory 4g --conf spark.driver.extraClassPath=/opt/seqr/.conda/envs/py37/lib/python3.7/site-packages/hail/hail-all-spark.jar --conf spark.executor

问题 I am tasked with building profibus master and slave network using Rpi and Rs-485 convertor . One Rpi will be master and other will be slave. I am using https://github.com/mbuesch/pyprofibus for DP-stack to implement the same. How can I assign address to master and slave rpi boards to use in profibus initialization sequence . It is not accepting the IP address given to the rpi boards 回答1: Since you talk about IP addresses I think you may be mistaken Profibus with Profinet. If that's the case
