Nutch 2.3 runtime error

Dear All,

I'm getting this error while trying to crawl website:

2015-01-26 11:56:39,498 ERROR zookeeper.RecoverableZooKeeper - ZooKeeper
exists failed after 3 retries

2015-01-26 11:56:39,498 WARN  zookeeper.ZKUtil - hconnection Unable to set

        at

It is Nutch 2.3 with MySQL configurations.

Any idea how can I overcome this?

Best

Hi Shadi,

I think your settings are worn. In traceback it uses HBase. Can you
check your configuration ? BTW As I know as Nutch 2.3 does not support
Mysql store.
