Hi,
We can read segments fine from the local disk like this:
bin/nutch readseg -list 20140102161258 -nocontent -nogenerate
NAME GENERATED FETCHER START FETCHER END
FETCHED PARSED
20140102161258 0 2014-01-02T16:13:09 2014-01-02T16:20:39
1227 1096
But we get the following exception when reading the same segment in distributde
mode:
bin/nutch readseg -list 20140102161258 -nocontent -nogenerate
Exception in thread "main" java.lang.NullPointerException

Can anyone confirm this issue?
Thanks,
