Change subject: Raise HDFS's namenode maximum jvm heap size to 6G ...................................................................... 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).
