Below is the code which i tried but there is an error please let me know where i am going wrong. 

     library("RJDBC") 
    .jinit()
    .jaddClassPath("/home/r_work/hive_service.jar")
    .jaddClassPath("/home/r_work/HiveJDBC4.jar")
    .jaddClassPath("/home/r_work/libfb303-0.9.0.jar")
    .jaddClassPath("/home/r_work/libthrift-0.9.0.jar")
    .jaddClassPath("/home/r_work/log4j-1.2.14.jar")
    .jaddClassPath("/home/r_work/hive_metastore.jar")
    .jaddClassPath("/home/r_work/ql.jar")
    .jaddClassPath("/home/r_work/slf4j-api-1.5.8.jar")
    .jaddClassPath("/home/r_work/slf4j-log4j12-1.5.8.jar")
    .jaddClassPath("/home/r_work/TCLIServiceClient.jar")
    .jclassPath()

    drv = JDBC("com.cloudera.hive.jdbc4.HS2Driver","~/r_work/hive_service.jar;~/r_work/HiveJDBC4.jar;~/r_work/libfb303-0.9.0.jar;~/r_work/libthrift-0.9.0.jar;~/r_work/log4j-1.2.14.jar;~/r_work/hive_metastore.jar;~/r_work/ql.jar;~/r_work/slf4j-api-1.5.8.jar;~/r_work/slf4j-log4j12-1.5.8.jar;~/r_work/TCLIServiceClient.jar","`")

    #drv = JDBC("com.cloudera.hive.jdbc4.HS2Driver","~/r_work/HiveJDBC4.jar","`")

    conn <- dbConnect(drv, "jdbc:hive2://grbd.com:10000/test_hive_db;AuthMech=1;KrbRealm=INTRANET.BARCAPINT.COM;KrbHostFQDN=grbd.com;KrbServicename=hive")

    #conn <- dbConnect(drv, "jdbc:hive2://grbdwhd0017.intranet.barcapint.com:10000;AuthMech=1;KrbRealm=INTRANET.BARCAPINT.COM;KrbHostFQDN=grbdwhd0017.intranet.barcapint.com;KrbServicename=hive")

     library(RHive)

you can simply connect to hiveserver2 from R using RHIVE package

below are the commands that i had used.

Sys.setenv(HIVE_HOME="/usr/local/hive") Sys.setenv(HADOOP_HOME="/usr/local/hadoop") rhive.env(ALL=TRUE) rhive.init() rhive.connect("localhost")
