Please refer this article if the Teradata TPT ingestion is stuck while running the below TPT command
Running TPT command source /home/hadoop/infoworks/infoworks/conf/tpt.sh ; tbuild -h 10M -j b010c3b214e589e065baafa8_922d91ee7900478dbdd265770249c9fbDUR_RESPONSE_PRESCRIBER -f /home/hadoop/infoworks/infoworks//temp/tpt/scripts/b010c3b214e589e065baafa8_922d91ee7900478dbdd265770249c9fbDUR_RESPONSE_PRESCRIBER.txt -r /home/hadoop/infoworks/infoworks//temp/tpt/checkpoints/ -L /home/hadoop/infoworks/infoworks//temp/tpt/logs/ -R 2
This issue occurs if the infoworks user doesn't have write permissions on the log file ( In this scenario it is: b010c3b214e589e065baafa8_922d91ee7900478dbdd265770249c9fbDUR_RESPONSE_PRESCRIBER.out ) to which the TPT command is trying to write its output/log. Due to this the job would not fail but it would be running forever.
Cancel the ingestion job. Make infoworks user the owner of the log file and then run the TPT ingestion again.
