[jira] [Updated] (SPARK-26499) JdbcUtils.makeGetter does not handle
ByteType
[ https://issues.apache.org/jira/browse/SPARK-26499?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Thomas D'Silva updated SPARK-26499:
-----------------------------------
Description:
I am trying to use the DataSource V2 API to read from a JDBC source. While using {{JdbcUtils.resultSetToSparkInternalRows}} to create an internal row from a ResultSet that has a column of type TINYINT I ran into the following exception
{code:java}
java.lang.IllegalArgumentException: Unsupported type tinyint
at org.apache.spark.sql.execution.datasources.jdbc.JdbcUtils$.org$apache$spark$sql$execution$datasources$jdbc$JdbcUtils$$makeGetter(JdbcUtils.scala:502)

{code}
This happens because ByteType is not handled in {{JdbcUtils.makeGetter}}.

This happens because ByteType is not handled in {{JdbcUtils.makeGetter}}.
Also, since {{JdbcUtils.getCommonJDBCType}} maps ByteType to TinyInt, I think {{getCatalystType}} should map TINYINT to ByteType (it currently maps TINYINT to IntegerType).
Summary: JdbcUtils.makeGetter does not handle ByteType (was: JdbcUtils.getCatalystType maps TINYINT to IntegerType instead of ByteType)
