hi
i want to execute wordcount example of hadoop in apache ignite. i have used
apache-ignite-hadoop-2.6.0-bin for execute map reduce tasks. my
default-config.xml in apache-ignite-hadoop-2.6.0-bin/config folder is just
as bellow:

i have run an ignite node with bellow command in command line in linux
ubuntu:
*/usr/local/apache-ignite-hadoop-2.6.0-bin/bin/ignite.sh
/usr/local/apache-ignite-hadoop-2.6.0-bin/config/default-config.xml*
after starting ignite node i execute a wordcount example in hadoop for
ruuning in ignite with bellow command:
*./hadoop jar
/usr/local/hadoop/share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.7.jar
wordcount /input/hadoop output2*
but after executing above command i have encounter an error just as attached
