Description

Impala hdfs-fs-cache values for namenode address and namenode port should be read from Impala's core-site.xml file rather than input as command line args. If these args are not specified when impalad starts, then it defaults to localhost:20500 which can be confusing.

Definition:
./be/src/runtime/hdfs-fs-cache.cc:DEFINE_int32(nn_port, 20500, "namenode port");
./be/src/runtime/hdfs-fs-cache.cc:DEFINE_string(nn, "localhost", "namenode host");
