How can I config to access HDFS(namenode HA) with HiveConf class by using hive-common-1.2.1.jar? - hive

Question

Who knows why class HiveConf has no HADOOPCONF enum type in hive-common jar now?
I write code using hive-common-1.2.1.jar HiveConf class to access HDFS(HA namenode), and I get an error below.
I realized my code didn't config HADOOPCONF so it can't connect to HDFS, but there is no HADOOPCONF in hive-common-1.2.1.jar any more, I found previous version of hive-common has the HADOOPCONF.

OK, I resolved this issue.
Because the class HiveConf in hive-common jar load "hdfs-site.xml" from hadoop by default, if only you set the classpath pointed to the folder of "hdfs-site.xml" when you running it.
CLASSPATH=$CLASSPATH:/opt/modules/hadoop/conf
$JAVA -cp $CLASSPATH com.baofeng.data.writer.HiveHcatalogWriter
