I have configured gridgain-hadoop-os-6.6.2.zip, and followed steps as mentioned in docs/hadoop_readme.pdf . started gridgain using bin/ggstart.sh command, now am running a simple wordcount code in gridgain with hadoop-2.2.0. using command
hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/*-mapreduce-examples-*.jar wordcount /input /output
Steps I tried:
Step 1: Extracted hadoop-2.2.0 and gridgain-hadoop-os-6.6.2.zip file in usr/local folder and changed name for gridgain folder as "gridgain".
Step 2: Set the path for export GRIDGAIN_HOME=/usr/local/gridgain.. and path for hadoop-2.2.0 with JAVA_HOME as
# Set Hadoop-related environment variables
export HADOOP_PREFIX=/usr/local/hadoop-2.2.0
export HADOOP_HOME=/usr/local/hadoop-2.2.0
export HADOOP_MAPRED_HOME=/usr/local/hadoop-2.2.0
export HADOOP_COMMON_HOME=/usr/local/hadoop-2.2.0
export HADOOP_HDFS_HOME=/usr/local/hadoop-2.2.0
export YARN_HOME=/usr/local/hadoop-2.2.0
export HADOOP_CONF_DIR=/usr/local/hadoop-2.2.0/etc/hadoop
export GRIDGAIN_HADOOP_CLASSPATH='/usr/local/hadoop-2.2.0/lib/*:/usr/local/hadoop-2.2.0/lib/*:/usr/local/hadoop-2.2.0/lib/*'
Step 3:
now i run command as bin/setup-hadoop.sh ... answer Y to every prompt.
Step 4:
started gridgain using command
bin/ggstart.sh
Step 5:
now i created dir and uploaded file using :
hadoop fs -mkdir /input
hadoop fs -copyFromLocal $HADOOP_HOME/README.txt /input/WORD_COUNT_ME.
txt
Step 6:
Running this command gives me error:
hadoop jar $HADOOP_HOME/share/hadoop/mapreduce/*-mapreduce-examples-*.
jar wordcount /input /output

I configured exactly the versions you mentioned (gridgain-hadoop-os-6.6.2.zip + hadoop-2.2.0) -- the "wordcount" sample works fine.
[UPD after question's author log analysis:]
Raju, thanks for the detailed logs. The cause of the problem are incorrectly set env variables
export HADOOP_MAPRED_HOME=${HADOOP_HOME}
export HADOOP_COMMON_HOME=${HADOOP_HOME}
export HADOOP_HDFS_HOME=${HADOOP_HOME}
You explicitly set all these variables to ${HADOOP_HOME} value, what is wrong. This causes GG to compose incorrect hadoop classpath, as seen from the below GG Node log:
+++ HADOOP_PREFIX=/usr/local/hadoop-2.2.0
+++ [[ -z /usr/local/hadoop-2.2.0 ]]
+++ '[' -z /usr/local/hadoop-2.2.0 ']'
+++ HADOOP_COMMON_HOME=/usr/local/hadoop-2.2.0
+++ HADOOP_HDFS_HOME=/usr/local/hadoop-2.2.0
+++ HADOOP_MAPRED_HOME=/usr/local/hadoop-2.2.0
+++ GRIDGAIN_HADOOP_CLASSPATH='/usr/local/hadoop-2.2.0/lib/*:/usr/local/hadoop-2.2.0/lib/*:/usr/local/hadoop-2.2.0/lib/*'
So, to fix the issue please don't set unnecessary env variables. JAVA_HOME and HADOOP_HOME is quite enough, nothing else is needed.
