......................................................................


Raise HDFS's namenode maximum jvm heap size to 6G

This is needed due to the unprecedented amount of files
currently stored in HDFS. The namenode daemon keeps
all metadata about inodes and data blocks in memory.
On the analytics100[12] nodes there is plenty of memory
completely free (not even used for Caching).
