## JIRA info

- Link: https://issues.apache.org/jira/browse/HUDI-4979
- Type: Bug

Start with HoodieBackedTableMetadataWriter.createMetadataWriteConfig and HoodieMetricsGraphiteConfig.Builder.usePrefix, then inspect HoodieConfig.setValue at the reported stack-trace lines. Reproduce the delete operation against the affected Hudi 0.11.1 table and determine why a null value reaches Properties.setProperty; done means the delete completes without this NullPointerException.
