Just to be sure that YARM/MR works fine on your setup, could you show the
output that is printed when you run an example MapReduce jobs?

$ hadoop jar <path-to-hadoop-mapreduce-jars>/hadoop-mapreduce-examples.jar
pi 10 100 # it runs PiEstimator example to estimate value of Pi


$ hadoop distcp /hbase /tmp/hbase-copy # it copies content from <src-dir> to

Last but not least, it's much more comfortable and easier to manage
Hadoop/HBase with distro like HDP or CDH. There are few reasons (1) they
make sure that the versions components (Hadoop, HBase, ZooKeeper, Hive etc.)
that you use are compatible, (2) they provide relatively smart default
configurations and recommendations, (3) they minimize the risk of
misconfiguration by deploying configuration changes to proper hosts, (4)
they install everything in proper order, directories and hosts, (5) they
give you monitoring, alerts, warnings etc.
