             Summary: Deprecate IndexWriterConfig's write lock timeout
                 Key: LUCENE-6525
                 URL: https://issues.apache.org/jira/browse/LUCENE-6525
             Project: Lucene - Core
          Issue Type: Task
            Reporter: Robert Muir


Followup from LUCENE-6508

We should ultimately remove this parameter, it is just sugar over a "sleeping lock factory" today that sleeps and retries until timeout, like the old code.

But really if you want a lock that blocks until its obtained, you can simply specify the sleeping lock factory yourself (and have more control over what it does!), or maybe an NIO implementation based on the blocking FileChannel.lock() or something else.

So this stuff should be out of indexwriter and not baked into our APIs.

I would like to:
1) deprecate this, mentioning to use the sleeping factory instead
2) change default of deprecated timeout to 0, so you only sleep if you ask. I am not really sure if matchVersion can be used, because today the default itself is also settable with a static setter <-- OVERENGINEERED
