Also here's the code comment which also says we don't need to download the
tlog's
{code:title=CdcrRequestHandler.java|borderStyle=solid}
ModifiableSolrParams solrParams = new ModifiableSolrParams();
solrParams.set(ReplicationHandler.MASTER_URL, masterUrl);
// we do not want the raw tlog files from the source
solrParams.set(ReplicationHandler.TLOG_FILES, false);
