the problem is that before
https://issues.apache.org/jira/browse/SOLR-2567, Solr invoked the
TieredMergePolicy "setters" *before* it tried to apply these 'global'
mergeFactor etc params.
So, even if you set them explicitly inside the<mergePolicy>, they
would then get clobbered by these 'global' params / defaults / etc.
I fixed this order in SOLR-2567 so that the settings inside the
<mergePolicy> *always* take precedence, e.g. they are applied last.
So, I think it might be difficult/impossible to configure this MP with
3.2 due to this.
That seems to be confirmed by my infostream. It's using
LogByteSizeMergePolicy whether I have mergeFactor configured or not.
The patch for SOLR-2567 applies with fuzz, but the result won't compile.
Unless I can find a way to patch 3.2 to allow using and configuring TMP,
I guess I'll just have to live with a two-pass optimize. It only adds a
few minutes to the process, and I currently have the disk space
available, so it's not the end of the world. I am seeing enough
improvements coming in 3.3 that I will have to lobby for upgrading to it
a couple of weeks after it gets released. It won't come out in time for
this cycle.
Thanks,
Shawn
