I was testing the standalone cluster installation and I followed the guide but my nodes was docker containers as following:
- The coordinator node with configured $path.dist as pdfs on my local storage
- Two executors node with configured $path.dist pdfs on my local storage
- All three nodes are docker containers on the same machine
- The $path.dist in the dreio.conf file for all nodes(coordinator and executors) is the same mounted volume via docker
Everthing was perfect and when I checked the running nodes vi dremio UI, all the referred nodes were working properly. The issue happened when I tried to create raw reflection for one of my datasets. The issue was each row was created twice and when I added a new node by the same way, ech row was created thrice and so on
