----------------------------------------
Hi [~sergeychugunov],
I tried to adapt your code early in IGNITE-13190 and have a few notes:
* when you start your node clean, maintenance record file won't be created. Is
this by design? Such detail makes writing tests a bit harder, you should
manually start maintenance component one more time.
* it's impossible to pass empty string or null into record parameters. For
example, if my record doesn't have any parameters, it won't work. Problem is in
the way you split that string from maintenance file.

> clearing corrupted PDS files.

> Project: Ignite
> Issue Type: New Feature
> Components: persistence
> Affects Versions: 2.8.1
> Reporter: Sergey Chugunov
> Assignee: Sergey Chugunov
> Priority: Critical
> Labels: IEP-53
> Fix For: 2.10
>
> Original Estimate: 168h
> Time Spent: 10m
> Remaining Estimate: 167h 50m
>
> If node with persistence is stopped when WAL was disabled for a cache (no
> matters because of rebalancing in progress or by explicit user request) on
> next node start all data files of that cache are removed automatically and
> unconditionally.
> This behavior may be unexpected for users as they may not understand all
> consequences of disabling WAL locally (for rebalancing) or globally (via
> IgniteCluster API call). Also it is not smart enough as there is no point in
> deleting consistent data files.
> We should change this behavior to the following list: no automatic deletions
> whatsoever. If data files are consistent (equivalent to: no checkpoint was
> running when node was stopped) start up normally. If data files are
> corrupted, don't let the node start.
