Subject RE: AcculumoFileOutputFormat class cannot be found by child jvm
Date Tue, 22 May 2012 22:21:28 GMT
Here is the exec string.  As you can see the illusive jars are on the list, but the child jvm
didn't get the memo on where they are.  The jars did not appear in the taskTracker or JobTracker
directories.  The paths are correct to the jar files on the local file system.

exec /cloudbase/hadoop-0.20.2/bin/hadoop jar /mnt/hgfs/CSI.Cloudbase/Java/CloudbaseServices/out/artifacts/CloudbaseIngesters/CloudbaseIngesters.jar
com.comcept.cloudbase.ingesters.placemarks.PlacemarkIngester -libjars "/cloudbase/accumulo-1.4.0/lib/libthrift-0.6.1.jar,/cloudbase/accumulo-1.4.0/lib/accumulo-core-1.4.0.jar,/cloudbase/zookeeper-3.4.3/zookeeper-3.4.3.jar,/cloudbase/accumulo-1.4.0/lib/cloudtrace-1.4.0.jar,/mnt/hgfs/CSI.Cloudbase/Java/CloudbaseServices/out/artifacts/CloudbaseIngesters/CloudbaseIngesters.jar,/usr/lib/ncct/kxml2-2.3.0.jar,/usr/lib/ncct/xmlpull-1.1.3.1.jar,/usr/lib/ncct/xstream-1.4.1.jar,/cloudbase/accumulo-1.4.0/lib/accumulo-core-1.4.0.jar,/cloudbase/accumulo-1.4.0/lib/commons-collections-3.2.jar,/cloudbase/accumulo-1.4.0/lib/commons-configuration-1.5.jar,/cloudbase/accumulo-1.4.0/lib/commons-io-1.4.jar,/cloudbase/accumulo-1.4.0/lib/commons-jci-core-1.0.jar,/cloudbase/accumulo-1.4.0/lib/commons-jci-fam-1.0.jar,/cloudbase/accumulo-1.4.0/lib/commons-lang-2.4.jar,/cloudbase/accumulo-1.4.0/lib/commons-logging-1.0.4.jar,/cloudbase/accumulo-1.4.0/lib/commons-logging-api-1.0.4.jar"

When I set up a DistributedCache on hdfs:// and added these jars to the job configuration
the child jvm found them just fine.

It looks like tool.sh is attempting to parse explicit libjars, but it might not be working
correctly.  The second-to-last line of tool.sh is

#echo exec "$HADOOP_HOME/bin/hadoop" jar "$TOOLJAR" $CLASSNAME -libjars \"$LIB_JARS\" $ARGS

If you could uncomment this line and send us what it displays, it might give us some insight
into where tool.sh is going wrong.  The -libjars are supposed to include the user-specified
libjars as well as accumulo-core, zookeeper, etc.
