> Sometime after Solr 4.9, the `MapReduceIndexerTool` got busted because
> invalid `solr.xml` contents were being written to the solr home dir zip. My
> guess is that a 5.0 change made the invalid file start to matter.
> The error manifests as:
> {code:java}
> Error: java.lang.IllegalStateException: Failed to initialize record writer

> The last version that I've successfully used `MapReduceIndexerTool` was 4.9,
> and I verified that this patch resolves the issue for me (testing on 5.1). I
> spent a couple hours trying to write a simple test case to exhibit the error,
> but I haven't quite figured out how to deal with the
> {noformat}java.security.AccessControlException: java.io.FilePermission
> ...{noformat} errors.
