Vu Hoang commented on NUTCH-780:
--------------------------------

add lines below into class org.apache.nutch.crawl.Crawl
{code:java|title=org/apache/nutch/crawl/Crawl.java|borderStyle=solid}
public static Configuration nutchConfig = null;
public static void setNutchConfig(Configuration config) { nutchConfig = config; }
{code}

and re-configure nutch configuration inside of method main as below
{code:java|title=org/apache/nutch/crawl/Crawl.java|borderStyle=solid}
Configuration conf = null;
if (nutchConfig != null) conf = nutchConfig;
else conf = NutchConfiguration.createCrawlConfiguration();
{code}
