Subject how can I access HDFS(namenode HA) by using hive-common-1.2.1.jar??
Date Thu, 19 May 2016 12:45:18 GMT
Hi guys,

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, I found previous version of hive-common has the
HADOOPCONF [
http://www.docjar.com/html/api/org/apache/hadoop/hive/conf/HiveConf.java.html
].

My question is how can I access HDFS by using hive-common-1.2.1.jar??

Thank you !!!
