I wrote mysql config to gora.properties and update sql lib in ivy.xml.
but when I run the command:
bin/crawl urls/seed.txt Test http://127.0.0.1:8080/solr 2
it throws exception:
[root#li257-46 local]# bin/crawl urls/seed.txt Test http://127.0.0.1:8080/solr 2

First, I think the avro jar not add, but I found the jar in lib:
/home/work/nutch2/runtime/local/lib
[root#li257-46 lib]# ls
avro-1.7.6.jar
avro-compiler-1.7.6.jar
avro-ipc-1.7.6.jar
avro-mapred-1.7.6.jar
Can you help me?
