Hi Gaurav,

When you are running all on a single node it is very common that multiple services are fighting for (scarce) available memory. Services like Hbase tend to fail when this happens.

You could try to be selective on what services you run concurrently. For instance if you just want to run Metron services, shut down Ambari Metrics, Oozie, Spark, Zeppelin and maybe Yarn and Hive cause you don't need it. You have to compromise when running single node.

For Metron make sure HDFS, Zookeeper, HBase, Kafka, Storm, ES and Kibana are up and OK.
