> 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
> Affects Versions: 2.0.0-M1, 2.0.0-M2, 2.0.0-M3, 2.0.0-M4, 2.0.0, 2.1.0,
> 2.2.0, 2.3.0
> Reporter: Ruben Van Wanzeele
> Priority: Major
>
> 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:
> https://lists.apache.org/thread/5v59hbp18rpsboqc2q6f79h3b64803om
