Collibra DQ User Guide

Command Line

We've moved! To improve customer experience, the Collibra Data Quality User Guide has moved to the Collibra Documentation Center as part of the Collibra Data Quality 2022.11 release. To ensure a seamless transition, will remain accessible, but the DQ User Guide is now maintained exclusively in the Documentation Center.

Scale + Data Science

Where Scale meets Data Science. Scale linearly with your data by adding executors and/or memory
-f "file:///Users/home/salary_data.csv" \
-d "," \
-rd "2018-01-08" \
-ds "salary_data"
-numexecutors 2 \
-executormemory 2g

Yarn Master

If Owl is run on an edge node on a popular hadoop distribution such as HDP, CDH, EMR it will automatically register the jobs with Yarn Resource Manager.

Spark Master

Owl can also run using spark master by using the -master input and passing in spark:url

Spark Standalone

Owl can run in standalone most but naturally will not distribute the processing beyond the hardware it was activated on.
spark deploymode option
driver memory example 3G for local space
spark executor cores
spark executor memory option example 3G
overrides local[*], i.e. spark://myhost:7077, yarn-client, yarn-cluster
kerberos principal name ex: [email protected]

Use Spark-Submit directly bypassing OwlCheck
