Mohammad Kamrul Islam commented on HADOOP-11090:
------------------------------------------------
Yes.
We are running everything with Java 8. As it is running, we want to find out
the issues or better configurations.
We will post the findings as we go.
In short, things are ok except : heap and VM usages are little higher in some
instances.Our team is working to get handle of this.
