Issues in lab 5: hdfs_2gram_data_load

[samkabue]

• the link '(see Hadoop v1 Installation)' is broken (it points to https://github.com/MIDS-scaling-up/coursework/blob/master/week5/hw/version_1/README.md) which is a 404
• after setup, /usr/local/hadoop/contrib/streaming/hadoop-streaming-1.2.1.jar (in Part 2: Load data) is not valid---maybe this should be updated to /usr/local/hadoop/share/hadoop/tools/lib/hadoop-streaming-2.7.1.jar?
• when I fix the previous issue with the suggested workaround, and then do 'Part 2: Load data', I get a lot of errors like the following:

  Container [pid=32025,containerID=container_1443213849013_0005_01_000002] is running beyond virtual memory limits. Current usage: 159.9 MB of 1 GB physical memory used; 2.2 GB of 2.1 GB virtual memory used. Killing container.
