Jobs Over 1 Million Records

If you have a large job (anything over 1 million records) the last step before running the job is increasing heap memory. Click the "Use Specific JVM arguments" check box and double click the "–Xmx1024mb argument". Change this to -Xmx4G to ensure proper performance when processing very large jobs over 1 million records.

Out of Memory Error

If you recieve this error:

java.lang.OutOfMemoryError: Java heap space

This means your job is a large job and you need to increase the heap memory. Please see Jobs Over 1 Million Records for more information.

NoClassDefFoundError: Integer

If you receive this error:

java.lang.NoClassDefFoundError: Integer

This means that one of your input columns is set to integer rather than string. To resolve this issue, please validate that the input schema are all set to string data types and try to run the job again.
