Subject RE: Nutch 2 and Cassandra
Date Tue, 02 Aug 2011 21:36:16 GMT
I did run into a couple more problems running Nutch 2 with CDH3. See https://issues.apache.org/jira/browse/NUTCH-937.
I added a comment on the thread explaining my additional problem. I worked around the problem
by unjarring the nutch-2-dev.job and seeting the HADOOP_CLASSPATH (see below) environment
variable. Not an ideal solution, but it works.

In order to run Nutch 2 on CDH3 I added the following to nutch-site.xml and rebuilt the nutch-2-dev.job:

    <property>
        <name>mapreduce.job.jar.unpack.pattern</name>
        <value>(?:classes/|lib/|plugins/).*</value>
    </property>

    <property>
        <name>plugin.folders</name>
        <value>${job.local.dir}/../jars/plugins</value>
    </property>

And I had to set this environment variable to my expanded plugins folder:

export HADOOP_OPTS="-Djob.local.dir=/<MY HOME>/nutch/plugins"

Hi

I've been watching progress on this thread with interest and think that this would be a great
addition to the wiki under the following page [1]

I am happy to write it up, however is there anything else we need to be aware of in addition
to the material you have provided, for example some latent info that has been assumed or not
been explained.

Thank you

I found the problem. I am using Cloudera CDH3 and it has a hue plugins jar with an older thrift
library in it. I removed the jar from my classpath and all is good. Thanks for your help.

OK... Are you running with a clustered version of Hadoop? I think you have to have your HADOOP_HOME
env variable set. Otherwise it runs in local mode. I have been able to run in local mode,
but not in deployed mode.
