Description

The test fails with a cast error due to the following commit.

65bfde5 2015-03-03 wheat9@apa o HDFS-6565. Use jackson instead jetty json in hdfs-client. Contributed by Akira AJISAKA.

toJsonMap inserts xferPort as an integer.

m.put("xferPort", datanodeinfo.getXferPort());

Then toDatanodeInfo tries to cast the Integer object to a Long.

tmpValue = m.get("xferPort");
int xferPort = (tmpValue == null) ? -1 : (int)(long)(Long)tmpValue;

The test passes in trunk due to HDFS-8080. Since HDFS-8080 is too large to pull into 2.7.1 we'll fix the cast issue.
