[jira] [Created] (IGNITE-9741) SegmentArchivedStorage and SegmentCompressStorage remain `iterrupted` after de-activation occurs before activation

Maxim Muzafarov created IGNITE-9741:
---------------------------------------

             Summary: SegmentArchivedStorage and SegmentCompressStorage remain `iterrupted` after de-activation occurs before activation
                 Key: IGNITE-9741
                 URL: https://issues.apache.org/jira/browse/IGNITE-9741
             Project: Ignite
          Issue Type: Bug
    Affects Versions: 2.6
            Reporter: Maxim Muzafarov
             Fix For: 2.7


The {{FileWriteAheadLogManager}} now contains:
 {{private final SegmentAware segmentAware;}}

 

The SegmentAware have the `interrupt()` method:
{code:java|title=SegmentAware:216}
    /**
     * Interrupt waiting on related objects.
     */
    public void interrupt() {
        segmentArchivedStorage.interrupt();

        segmentCompressStorage.interrupt();

        segmentCurrStateStorage.interrupt();
    }
{code}
 

Method at the {{FileWriteAheadLogManager}} de-activation sets (e.g. for SegmentArchivedStorage) `interrupted` filed to `true` value but never revert it to `false` after activation.
{code:java|title=SegmentArchivedStorage:114}
    /**
     * Interrupt waiting on this object.
     */
    synchronized void interrupt() {
        interrupted = true;

        notifyAll();
    }
{code}
 

So, the SegmentArchivedStorage after de-activation always remain interrupted. 
 This can lead to undefined behaviour e.g. exchange worker hangs.
