Slf4j Error when connecting to Dremio

Hello Team Helical,

I am using Dremio to connect Helical Insight to ElasticSearch. However, I am getting Slf4j StaticLoggerBinder error when I try to connect. Can you give me a fix for this?

“LinkageError: Loader constraint violation: when resolving method “org.slf4j.impl.StaticLoggerBinder.getLoggerFactory….”


Thank You

Hello Tarun,

When you uploaded the Dremio driver into Helical Insight application, it also has slf4j.jar file.
Before uploading make sure you remove SLF4J before uploading because it is already available in Helical Insight application.
Steps to remove slf4j from dremio JDBC driver

  1. Download jar file from the provided link
  2. Right click on jar file
  3. Click on open with winRARarchiver/ 7-Zip tool
  4. Click on org folder select slf4j and delete slf4j folder
  5. Close winRARarchiver/ 7-Zip tool
  6. Now upload dremio jar file without slf4j to Helical Insight Application

Thank You
