---------------------------------------
Fix Version/s: (was: 2.9)
> Disabling WAL Archiving via setting walArchivePath to walPath isn't worked as
> expected
> --------------------------------------------------------------------------------------
>
> Key: IGNITE-10840
> URL: https://issues.apache.org/jira/browse/IGNITE-10840
> Project: Ignite
> Issue Type: Bug
> Components: general
> Affects Versions: 2.6
> Reporter: Andrey Aleksandrov
> Priority: Major
> Attachments: Result.png, config1.xml, config2.xml
>
>
> Description:
> 1)start the server node with separate wal and walArchive wait for the first
> archived segment.
> See config1.xml
> Code:
> Ignite ign = Ignition.start("examples/config/config1.xml");
> ign.cluster().active(true);
> IgniteCache<Integer, Integer> cache = ign.getOrCreateCache("default");
> for (int i = 0;; i++) {
> cache.put(i, i);
> if(i % 1000 == 0) {
> System.out.println(i);
> }
> }
> 2) Wait for the first archived segment.

> 3)stop the node
> 4)Change the walArchivePath to walPath as it described here:
> See config2.xml
> https://apacheignite.readme.io/docs/write-ahead-log#section-disabling-wal-archiving
> 5)Restart the node with updated configuration
> Ignite ign = Ignition.start("examples/config/config2.xml");
> ign.cluster().active(true);
> IgniteCache<Integer, Integer> cache = ign.getOrCreateCache("default");
> for (int i = 0;; i++) {
> cache.put(i, i);
> if(i % 1000 == 0) {
> System.out.println(i);
> }
> }
> As a result, walArchive will not be disabled and new segments will be store
> in WAL directory.
> In Ignite 2.6 it will be a reason for the next exception on next node restart:
> Caused by: class org.apache.ignite.IgniteCheckedException: Failed to
> initialize wal (work directory contains incorrect number of segments)
