Java's recent popularity?

It almost seems like Java's popularity has skyrocketed after the advent of hadoop and associated projects. Take a look at the recent projects: hadoop, hbase, cassandra, flume, kafka, etc. Large highly successful companies are using it extensively (LinkedIn, Netflix). And these are not our cookie-cutter enterprise projects. These are high performance applications. Wow! And the industry keeps talking about the death of Java. (I'm not Java fan; I used to program in C++ for more than 10 yrs until I found the dearth of internet companies - other than yahoo, google, facebook - who use C++). So I guess Java is here to stay for a pretty long time? Thoughts?
