Resolution

The mechanism to pass on a user name resolves the issue. Here is the example of the passing the connection string which works for rhive.

library(RHive)
Sys.setenv(HADOOP_CONF_DIR="/etc/hadoop/conf")
Sys.setenv(RHIVE_HIVESERVER_VERSION="2")
Sys.setenv(HIVE_HOME="/usr/hdp/current/hive-client")
Sys.setenv(HADOOP_HOME="/usr/hdp/current/hadoop-client")
rhive.init()
rhiveConnection<-rhive.connect(host="127.0.0.1", port=10000, hiveServer2=NA, defaultFS=NULL, updateJar=FALSE, user="hive", password=NULL, db="default", properties = character(0))

NOTE: Ensure following parameters are set correctly

  • JAVA_HOME
  • PATH should pick our JAVA_HOME's binary so "export PATH=$JAVA_HOME/bin:${PATH}"
  • Rhive looks for binaries, thus when setting the HIVE_HOME and HADOOP_HOME, ensure that hive-client and hadoop-client directories are being picked.
  • Verify environment variables for rhive using rhive.env()
  • Very important to use doube quotes "" for enclosing the string/character values, like user/database name
