I'm trying locally a hadoop script that works with nutch.job, where it
doesn't work as follows:
nutch/runtime/deploy/bin/nutch inject gabriele/crawl/crawldb/0
gabriele/crawl/seeds/it_seeds
Exception in thread "main" java.lang.NoClassDefFoundError:
org/apache/hadoop/mapred/JobConf
at java.lang.Class.forName0(Native Method)
at java.lang.Class.forName(Class.java:247)
at org.apache.hadoop.util.RunJar.main(RunJar.java:180)
Caused by: java.lang.ClassNotFoundException:
org.apache.hadoop.mapred.JobConf

... 3 more
I'm aware of NUTCH-843 <https://issues.apache.org/jira/browse/NUTCH-843> and
also can get the script to work using runtime/local but examining
runtime/deploy/bin/nutch it seems planned to automatically adapt to local in
absence of hadoop cluster, and hence would prefer if the same script worked
both locally and on the cluster.
