Pavel Voronkin updated IGNITE-10671:
------------------------------------
Description:
Race is painful when you switch your cluster from walCompaction=false to
walCompaction=true.
The same FileCompressor instance will use different segmentAwares due to
start0() is called twice which leads to inconsistent behaviour and errors
during compaction, basically we will try to archive files twice concurrently.
> Double initialization of segmentAware and FileArchiver lead to race breaking
> file compression.
