---------------------------------
Labels: bulk-closed (was: )
> "No suitable driver" on first try
> ---------------------------------
>
> Key: SPARK-19209
> URL: https://issues.apache.org/jira/browse/SPARK-19209
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.1.0
> Reporter: Daniel Darabos
> Priority: Critical
> Labels: bulk-closed
>
> This is a regression from Spark 2.0.2. Observe!
> {code}
> $ ~/spark-2.0.2/bin/spark-shell --jars org.xerial.sqlite-jdbc-3.8.11.2.jar
> --driver-class-path org.xerial.sqlite-jdbc-3.8.11.2.jar
> [...]
> scala> spark.read.format("jdbc").option("url",
> "jdbc:sqlite:").option("dbtable", "x").load
> java.sql.SQLException: [SQLITE_ERROR] SQL error or missing database (no such
> table: x)
> {code}
> This is the "good" exception. Now with Spark 2.1.0:
> {code}

> [...]
> scala> spark.read.format("jdbc").option("url",
> "jdbc:sqlite:").option("dbtable", "x").load

> Simply re-executing the same command a second time "fixes" the {{No suitable
> driver}} error.
> My guess is this is fallout from https://github.com/apache/spark/pull/15292
> which changed the JDBC driver management code. But this code is so hard to
> understand for me, I could be totally wrong.
> This is nothing more than a nuisance for {{spark-shell}} usage, but it is
> more painful to work around for applications.
