Feature Changes in This Release

  • Load Error Diagnostics Available Through an SQL Client

    Two new Oracle SQL Connector for HDFS properties enable you to identify and review data load errors from within your SQL client, as an alternative to examining the .log and .bad files directly.

    See oracle.hadoop.exttab.badFileFormatUsePercentA and oracle.hadoop.exttab.logFileFormatUsePercentA in this guide. These properties can create diagnostic external tables over .log and .bad files that you can use to determine whether the load was successful or to review the reason for any rejected rows.
