Re: Failure when running Behemoth Tika extraction job

[DigitalPebble]

Hi Anupam,

Behemoth is built on the Hadoop 1.x branch and it seems that there is a conflict between the versions indeed. There have been improvements to the code since adding the patch so I'd recommend that you revert the change in https://github.com/DigitalPebble/behemoth/commit/40497b3f081d7f92ae0ae78691af255fadc2f78a and recompile. You should be able to download the previous version of this class from https://github.com/DigitalPebble/behemoth/blob/8a6b1c41ea782069771d80cf7b943cb84b36d20f/tika/src/main/java/com/digitalpebble/behemoth/tika/TikaProcessor.java

There is no guarantee that you won't have other such conflicts though.

Hope it helps

Julien

Hi,

I am using CDH4 on ubuntu in a single pseudo-distributed mode. And then running behemoth-tika text extraction job -
~/behemoth-master/tika/target$ hadoop jar ./behemoth-tika-*-job.jar com.digitalpebble.behemoth.tika.TikaDriver -i "hdfs://user/xxx/nutch-output" -o "hdfs://user/xxx/tika-output"

But I am getting quite a few exceptions, initial exceptions on the stack trace being ClassNotFoundException for org.apache.hadoop.mapred.Counters$CountersExceededException


There seems to be incompatibility between Behemoth (1.0.0 built from the zip download) code and the version of hadoop-core*.jar shipped with CDH4. I checked on my installation and see that CountersExceededException class doesn't exist in /usr/lib/hadoop-0.20-mapreduce/hadoop-core-2.0.0-mr1-cdh4.1.2.jar .

This class exists in a different hadoop version - hadoop-core-1.0.4.jar, so I guess the behemoth code is compatible with that version.

Is there a way around it without reverting to a different hadoop installation ( hadoop-core-1.0.4.jar)? Also I see that CountersExceededException was added to the code in behemoth recently. Can you guide me to a version of stable behemoth source without CountersExceededException check ?

regards,
Anupam.
