当我打开R时，
library(Rserve) Rserve(args="--no-save")
Sys.setenv(HADOOP_HOME="/home/hadoop/hadoop-1.2.1")
Sys.setenv(HIVE_HOME="/usr/local/hive")
library(RHive)
rhive.connect()
我收到以下错误，连接失败。请帮帮我。
Warning:
+----------------------------------------------------------+
+ / hiveServer2 argument has not been provided correctly. +
+ / RHive will use a default value: hiveServer2=TRUE. +
