I solved the problem by myself. Is it ignite's bug? Though I have set the following variable in .bashrc, ignite still can't get the related hadoop jar.
*export IGNITE_LIBS=$IGNITE_LIBS:"$IGNITE_HOME/libs/*":$HADOOP_CLASSPATH* Now I have solved this problem by copying related hadoop jars mannually: cp $HADOOP_HOME/share/hadoop/common/hadoop-common-2.7.2.jar $IGNITE_HOME/libs cp $HADOOP_HOME/share/hadoop/common/lib/commons* $IGNITE_HOME/libs cp $HADOOP_HOME/share/hadoop/common/lib/guava-11.0.2.jar $IGNITE_HOME/libs cp $HADOOP_HOME/share/hadoop/mapreduce/hadoop-mapreduce-client-core-2.7.2.jar $IGNITE_HOME/libs -- View this message in context: http://apache-ignite-users.70518.x6.nabble.com/Failed-to-running-hadoop-accelerator-tp9174p9184.html Sent from the Apache Ignite Users mailing list archive at Nabble.com.
