Vladislav Pyatkov commented on IGNITE-15755:
--------------------------------------------
In additional, I want that the all paths where the RAFT log stored should be
suitable for Windows.
At the moment, I am getting an exception when start any test from
ITDynamicTableCreationTest.

> Unable to clear raft log on raft node stop in jraft
> ---------------------------------------------------
>
> Key: IGNITE-15755
> URL: https://issues.apache.org/jira/browse/IGNITE-15755
> Project: Ignite
> Issue Type: Improvement
> Reporter: Alexander Lapin
> Priority: Major
> Labels: ignite-3
>
> h3. Problem
> In case of partition reassignment, meta storage reconfiguration or table drop
> it's required not only to cleanup data storage but also clear stable raft
> log. Currently there's no such method in api.
> h3. Possible Solution
> [~ascherbakov] suggested updating
> {code:java}
> org.apache.ignite.raft.jraft.RaftGroupService#shutdown{code}
> with {color:#1d1c1d}boolean cleanupState{color} flag
> {code:java}
> org.apache.ignite.raft.jraft.RaftGroupService#shutdown(boolean
> cleanupState){code}
> RAFT initializes three different storage for a group:
> {code:java}
> nodeOptions.setLogUri(serverDataPath.resolve("logs").toString());
> nodeOptions.setRaftMetaUri(serverDataPath.resolve("meta").toString());
> nodeOptions.setSnapshotUri(serverDataPath.resolve("snapshot").toString())
> {code}
> when the RAFT group is dropping from node (assignment changed or table is
> dropped) all those directories have to remove from disk.
> Implementation requited:
> # Implement a method _LogStorage#destroy_, the method will clear storage
> folder.
> # Add an invocation of this method to API. It might add a _destroy_ flag to
> method RaftServer#stopRaftGroup or add another one method.
> # Write a test which demonstrate that folders don't exist after group
> destroyed.
