If you try and close again, the call will hang. If you are using > native locks and try to open a new IndexWriter, it will fail to get the lock. > If you try IW#forceUnlock, it wont work because the not fully closed IW will > still have the lock. > ideas: > * On ClosedByInterruptException, IW should continue trying to close what it > can and unlock the index? Generally I have see the exception trigger in > commitInternal. > * We should add a non static forceUnlock to IW that lets you remove the lock > and start a new IW? > * We should make the lock protected so IW sub classes could unlock the index > in advanced use cases? > * others? -- This message is automatically generated by JIRA.
