Problem Running 1.5.0 on Amazon EMR - dfs.support.append not true.

When trying to start tserver on Amazon EMR, you'll see the following
message in the logs:

2013-05-27 00:04:43,593 [tabletserver.TabletServer] FATAL: Must set
dfs.durable.sync OR dfs.support.append to true.  Which one needs to be set
depends on your version of HDFS.  See ACCUMULO-623.
HADOOP RELEASE          VERSION           SYNC NAME             DEFAULT
Apache Hadoop           0.20.205          dfs.support.append    false
Apache Hadoop            0.23.x           dfs.support.append    true
Apache Hadoop             1.0.x           dfs.support.append    false
Apache Hadoop             1.1.x           dfs.durable.sync      true
Apache Hadoop          2.0.0-2.0.2        dfs.support.append    true
Cloudera CDH             3u0-3u3             ????               true
Cloudera CDH               3u4            dfs.support.append    true
Hortonworks HDP           `1.0            dfs.support.append    false
Hortonworks HDP           `1.1            dfs.support.append    false

To resolve this, the property needs to be present when hadoop is configured
so that both slave and master are initialized correctly. I have not
discovered how to correct this issue.
