-----------------------------------------
Summary: Local state lost when migrating from 1.28 to 2.3
Key: NIFI-14392
URL: https://issues.apache.org/jira/browse/NIFI-14392
Project: Apache NiFi
Issue Type: Bug
Reporter: Ruben Van Wanzeele
We experienced an issue with the state during migration
Our local state-management configuration looks as follows:
{code:java}
<local-provider>
<id>local-provider</id>
<class>org.apache.nifi.controller.state.providers.local.WriteAheadLocalStateProvider</class>
<property name="Directory">./state/local</property>
<property name="Always Sync">false</property>
<property name="Partitions">16</property>
<property name="Checkpoint Interval">2 mins</property>
</local-provider> {code}
And before migration we have our state details correctly in the expected
directory:
{code:java}
ls -la ./state/local/
total 92
drwxrwsr-x. 18 nifi nifi 4096 Mar 26 10:25 .
drwxrwsr-x. 8 root nifi 4096 Jan 17 02:14 ..
drwxrwsr-x. 2 nifi nifi 4096 Mar 26 10:25 partition-0
drwxrwsr-x. 2 nifi nifi 4096 Mar 26 10:25 partition-1
drwxrwsr-x. 2 nifi nifi 4096 Mar 26 10:25 partition-10
drwxrwsr-x. 2 nifi nifi 4096 Mar 26 10:25 partition-11
...
drwxrwsr-x. 2 nifi nifi 4096 Mar 26 10:25 partition-8
drwxrwsr-x. 2 nifi nifi 4096 Mar 26 10:25 partition-9
-rw-r--r--. 1 nifi nifi 20448 Mar 26 10:25 snapshot
-rw-r--r--. 1 nifi nifi 0 Feb 19 21:28 wali.lock{code}
On a new environment with the same state-management configuration I see that
the state information is stored in ./state/local/journals directory:
{code:java}
ls -la ./state/local/
total 16
drwxrwsr-x 3 nifi nifi 4096 Mar 26 10:23 .
drwxrwsr-x 9 root nifi 4096 Mar 24 12:27 ..
-rw-r--r-- 1 nifi nifi 2443 Mar 26 10:23 checkpoint
drwxrwsr-x 2 nifi nifi 4096 Mar 26 10:23 journals {code}
On a migrated environment I find both directory structures, and {*}the state
from before 2.3 is not maintained{*}.
When searching the web, I found that this issue was already alerted, but not
yet officially reported:
