(Solved) spark-submit error Exception in thread “main” java.sql.SQLException: No suitable driver found

question

Executing spark-submit on linux reports an error that the driver cannot be found, but I can run it on the local idea, excluding code problems, it may be that linux does not place the mysql driver jar package

Solution

1. Find JAVA_HOME first

which java

2. enter ext

cd ~/jdk1.8.0_171/jre/lib/ext

3. Place the mysql driver jar package in this folder
   
4. Re-run
