Dennis Kliche created NIFI-7998: ----------------------------------- Summary: Parquet file reader service throws Nullpointer Exception Key: NIFI-7998 URL: https://issues.apache.org/jira/browse/NIFI-7998 Project: Apache NiFi Issue Type: Bug Affects Versions: 1.12.1 Environment: Docker build on Kubernetes Reporter: Dennis Kliche Attachments: Jira_Parquet_Error.json, image-2020-11-11-22-33-31-019.png, image-2020-11-11-22-41-13-099.png, image-2020-11-11-22-41-44-188.png
We have a pipeline that gets an parquet file and write it into a database via PutDatabase Record. The content of the flow file is a parquet file. If the flow file is processed we are getting a NullPointerException. !image-2020-11-11-22-33-31-019.png! After some tests I found out, that the processor works like expected but if the flowfile is a parquet file and the reader is a parquet reader it throws this error. To confirm that is has to do with the parquet reader, I used a very simple approach. Generate flowfile with JSON transform it to parquet and then back to JSON. This resulted in the same error message. In the attached Jira_Parquet_Error.json you can see my simple construction. Here you can see the settings of the parquet writer: !image-2020-11-11-22-41-13-099.png! Here you can see the settings of Parquet Reader !image-2020-11-11-22-41-44-188.png! Until update from 1.11.4 to 1.12.1 it worked. Since 1.12.1 we are getting this issue. -- This message was sent by Atlassian Jira (v8.3.4#803005)
