It is already solved, it was only missing in the CREATE TABLE to add the sandbox path CLD_ML_BI_ENG.iris dbExecute(conn = con_Hive,
statement = "CREATE EXTERNAL TABLE CLD_ML_BI_ENG.iris(sepal_length double, sepal_width double, petal_length double, petal_width double, species varchar(10))
ROW FORMAT SERDE 'org.apache.hadoop.hive.ql.io.orc.OrcSerde'
STORED AS INPUTFORMAT 'org.apache.hadoop.hive.ql.io.orc.OrcInputFormat'
OUTPUTFORMAT 'org.apache.hadoop.hive.ql.io.orc.OrcOutputFormat'
LOCATION '/sandbox/CLD_ML_BI_ENG/iris'")

I am trying to create a table using the CREATE TABLE statement, in hue it works perfectly but when I use the dbexecute function in r, I get an error. How could it be solved. library(DBI)
library(odbc)
con_Hive <- dbConnect(odbc::odbc(), "Hive_produccion", database = "cld_ml_bi_eng", encoding = "latin1")
con_Hive
dbExecute(conn = con_Hive, statement = "CREATE EXTERNAL TABLE iris(sepal_length double,
sepal_width double,
petal_length double,
petal_width double,
species varchar(10))
LOCATION '/sandbox/CLD_ML_BI_ENG/iris'")

I am using Rstudio and I need to save some tables in my sandbox, however I cannot specify the location, because by default we send the tables to the path: hdfs: //haprod/warehouse/tablespace/managed/hive/cld_ml_bi_eng.db/iris How can I specify the location when writing the table is in the LOCATION '/sandbox/CLD_ML_BI_ENG/iris' library(DBI)
library(odbc)
con_Hive <- dbConnect(odbc::odbc(), "Hive_produccion", database = "cld_ml_bi_eng", encoding = "latin1")
colnames(iris) <- gsub(pattern = "\\.", replacement = "_", x = colnames(iris))
dbWriteTable(conn = con_Hive, name = Id(schema = "cld_ml_bi_eng", table = "iris"), value = iris) LOCATION '/sandbox/CLD_ML_BI_ENG/iris'
