------------------------------------
Summary: NPE When Using JdbcIO.PoolableDataSourceProvider
Key: BEAM-8501
URL: https://issues.apache.org/jira/browse/BEAM-8501
Project: Beam
Issue Type: Bug
Components: io-java-jdbc
Affects Versions: 2.16.0
Environment: Dataflow Runner
Reporter: Mehdi Massoudi
When using a simple PoolableDataSourceProvider in the Dataflow Runner I get a
null pointer exception at runtime.
{code:java}
JdbcIO.<~>write()
.withDataSourceProviderFn(
JdbcIO.PoolableDataSourceProvider.of(
JdbcIO.DataSourceConfiguration
.create("org.postgresql.Driver", jdbcUrl)
.withUsername(jdbcUsername)
.withPassword(jdbcPassword)
)
)
{code}
