We have deployed BigInsights Quickstart edition with two nodes. The monitoring service shows unavailable on the UI. But when we run healthcheck from the backend all the components are started.
From the UI,
1) we tried to deploy four monitoring applications : Cluster Aggregation,data retention, down sampling and log collection
2) Ran the applications, data retention and log collection ran successful
3) Running the Cluster aggregation and down sampling gives error JA018 : Main class [org.apache.oozie.action.hadoop.PigMain], exit code 
4) Inspite of the above error, tried starting the monitoring service from the UI, the "write hbase status" shows as error.
Are there any configuration changes we are missing. Please help on this.
