Thanks for replying Prasad. [Shame on me] The problem has been solved.
I was following this tutorial : https://cwiki.apache.org/confluence/display/Hive/HiveClient And there is a script to run the HiveJdbcClient java aplication with the following script: #!/bin/bash HADOOP_HOME=/your/path/to/hadoop HIVE_HOME=/your/path/to/hive echo -e '1\x01foo' > /tmp/a.txt echo -e '2\x01bar' >> /tmp/a.txt *HADOOP_CORE={{ls $HADOOP_HOME/hadoop-*-core.jar}}* CLASSPATH=.:$HADOOP_CORE:$HIVE_HOME/conf for i in ${HIVE_HOME}/lib/*.jar ; do CLASSPATH=$CLASSPATH:$i done java -cp $CLASSPATH HiveJdbcClient The problem was setting the HADOOP_CORE var (bold remarked). In the current version of Hadoop (0.20.203.0) the core file is hadoop-core-0.20.203.0.jar. So changing the script to *HADOOP_CORE={{ls $HADOOP_HOME/hadoop-core-*.jar}} *would fix it.
