Subject [jira] [Commented] (LUCENE-3586) Choose a specific Directory implementation running the CheckIndex main

Hi Michael,

Actually I don't like all the generics required in CommandLineUtil solely to support LTC's
case; if not for LTC the util would be much simpler (just one method taking a String class
name/path and returning a Directory instance).

I see. But I think we were on the right track. Have a look at the last version, I kept the
merged code removing that method with generics. If you don't like even this version I'll go
back, no problem at all!

Can you add the lost " // for javadocs" comment on one of CheckIndex's imports?

Ops, I restored it.

> It should be possible to choose a specific Directory implementation to use during the
CheckIndex process when we run it from its main.
> What about an additional main parameter?
> In fact, I'm experiencing some problems with MMapDirectory working with a big segment,
and after some failed attempts playing with maxChunkSize, I decided to switch to another FSDirectory
implementation but I needed to do that on my own main.
> Should we also consider to use a FileSwitchDirectory?
> I'm willing to contribute, could you please let me know your thoughts about it?
