Dzianis Sokal created MAPREDUCE-6187:
----------------------------------------
Summary: DBInputFormat can't pick driver class from *-job.jar/lib
Key: MAPREDUCE-6187
URL: https://issues.apache.org/jira/browse/MAPREDUCE-6187
Project: Hadoop Map/Reduce
Issue Type: Bug
Reporter: Dzianis Sokal
Assume package structure:
{code}
myprocess-job.jar
/mypackage/MyProcess.class
/lib/ojdbc.jar
{code}
Where:
MyProcess.class sets up DbInputFormat.
If I call:
{code}
hadoop jar myprocess-job.jar mypackage.MyProcess.class
{code}
I will get ClassNotFoundException when DBConfiguration does
{code}
Class.forName(conf.get(DBConfiguration.DRIVER_CLASS_PROPERTY))
{code}
The fix may be:
{code}
conf.getClassByName(conf.get(DBConfiguration.DRIVER_CLASS_PROPERTY));
{code}
