Mark Payne created NIFI-892:
-------------------------------
Summary: If the "nifi.flowfile.repository.partitions" property is
changed to a smaller value, FlowFIles not restored properly
Key: NIFI-892
URL: https://issues.apache.org/jira/browse/NIFI-892
Project: Apache NiFi
Issue Type: Bug
Components: Core Framework
Reporter: Mark Payne
Assignee: Mark Payne
Priority: Critical
Fix For: 0.3.0
To recreate:
1. Start NiFi and run some data through it.
2. Kill NiFi (may not happen if the FlowFile repo was just checkpointed; the
logs would indicate this)
3. Change the "nifi.flowfile.repository.partitions" property in
conf/nifi.properties from 256 to 6
4. Restart NiFi
At this point, any updates to the Write-Ahead Log that occurred on journal-7
through journal-256 will be lost. This can cause some bizarre behavior, such as
FlowFiles that have finished processor could be reprocessed. FlowFiles could
also lose attributes (or could be re-processed without having all of their
attributes present).
