Hive Engine Logs

Hive Engine Logs

The Hive engine logs appear in the LDTM log and the Hive session log.
You can find the information about Hive engine log events in the following log files:
LDTM log
The LDTM logs the results of the Hive queries run for the mapping. You can view the LDTM log from the Developer tool or the Administrator tool for a mapping job.
Hive session log
For every Hive script in the Hive execution plan for a mapping, the Data Integration Service opens a Hive session to run the Hive queries. A Hive session updates a log file in the following directory on the Data Integration Service node:
<InformaticaInstallationDir>/tomcat/bin/disTemp/
. The full path to the Hive session log appears in the LDTM log.
