------------------------------------
Key: HIVE-1698
URL: https://issues.apache.org/jira/browse/HIVE-1698
Project: Hadoop Hive
Issue Type: Improvement
Components: Server Infrastructure
Affects Versions: 0.7.0
Reporter: Ted Yu
When newInstance() call fails in getInputFormatFromCache(), the exception isn't
displayed in the log.
java.io.IOException: Cannot create an instance of InputFormat class
org.apache.hadoop.mapred.TextInputFormat as specified in mapredWork!
It would help debug the issue by including the exception in log, e.g.:
