Unable to connect to jdbc using spark scala-CodePudding

Im trying to read data from jdbc in spark scala. Below is the code written in spark scala in Databricks.

val df = (spark
  .read
  .format("jdbc")
  .option("url", <connection-string>)
  .option("dbtable", <table-name>)
  .option("user", <username>)
  .option("password", <password>)
  .option("ssl", True)
  .option("sslmode", "require")
 .load()

Im getting the below error message.

java.sql.SQLNonTransientConnectionException: Could not connect to 10.6.8.86:3306 : PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Could someone please let me know how to resolve this issue.

CodePudding user response：

The certificate used by your host is not trusted by java.

Solution 1 (Easy, not recommended)

Disabled certificate checking and always trust the certificate provided by server.

Add trustServerCertificate property.

val df = (spark
  .read
  .format("jdbc")
  .option("url", <connection-string>)
  .option("dbtable", <table-name>)
  .option("user", <username>)
  .option("password", <password>)
  .option("ssl", True)
  .option("trustServerCertificate", True)
  .option("sslmode", "require")
 .load()

Solution 2 (Difficult, Recommended)

Get the certificate and store it in the trusted store of your system.
