R Programming 6: R on Hadoop Hive

Connection:
-> library(RHive)
Loading required package: rJava
Loading required package: Rserve
-> rhive.init(hiveHome="/usr/hdp/current/hive-client/",hadoopHome="/usr/hdp/current/hadoop-client")
-> rhive.connect(host="HS2",port=10000,defaultFS="hdfs://HiveCLI/R server:8020")

Extensions in R:
rhive.connect
fhive.query
rhive.assign
rhive.export
rhive.napply
rhive.sapply
rhive.aggregate
rhive.list.tables
rhive.load.table
rhive.desc.table
Ex:
rhive.desc.table("diva.tablename")

Setting hive.execution.engine as tez in R:
rhive.set('hive.execution.engine','tez')

input <- rhive.query("select * from db.tableanme limit 10")


Issues:

> hive.query("show tables")
Error: could not find function "hive.query"
> library(RHive)
> rhive.init(hiveHome="/usr/hdp/current/hive-client/",hadoopHome="/usr/hdp/current/hadoop-client")
> rhive.connect(host="HiveServer2",port=10000,defaultFS="hdfs://hiveClient:8020"
+ hive.query("show tables")
Error: unexpected symbol in:
"rhive.connect(host="HiveServer2",port=10000,defaultFS="hdfs://iveClient:8020"
hive.query"
