Replication Index Fetch error

[Eric Tang <er...@gmail.com>]

Hi,

I'm running a master-slave setup, both on 3.2, and am having an issue with
the slave node.

I promoted my old slave node to master, took down the old master, and made
it into a slave.  Now I can't get the new slave to fetch index.  There are
a little over a million documents in the index.

That did it.  I was running 3.3 on one and 3.4 on another.

Thanks!

According to http://lucene.apache.org/java/3_4_0/fileformats.html, the FNMVersion changed from -2 to -3 in Lucene 3.4. Is it possible that the new master is actually running 3.4, and the new slave is running 3.2? (This is just a wild guess.)
