hadoopVersion property
Applies only to Amazon EMR release versions earlier than 4.0. The Hadoop
version for the cluster. Valid inputs are "0.18" (no longer maintained),
"0.20" (no longer maintained), "0.20.205" (no longer maintained), "1.0.3",
"2.2.0", or "2.4.0". If you do not set this value, the default of 0.18 is
used, unless the AmiVersion parameter is set in the RunJobFlow
call, in which case the default version of Hadoop for that AMI version is
used.
