How do I add a jar using sparklyr? -


when try access hive table using rstudio , sparklyr using code:

library(sparklyr) library(dplyr) sys.setenv(spark_home="/usr/hdp/current/spark2-client") # got ambari spark2 configs sc <- spark_connect(master = "yarn-client", config = config, version = '2.1.0')  library(dbi) tabtweets <- dbgetquery(sc, "select * tweets0 limit 10")

i error:

error in value[[3l]](cond) :    failed fetch data: java.lang.runtimeexception: java.lang.classnotfoundexception: org.openx.data.jsonserde.jsonserde

this because tweets0 created using jsonserde. fixed, example, when encountered using hive cli by:

add jar /usr/hdp/2.4.2.0-258/hive/lib/json-serde-1.3.7-jar-with-dependencies.jar;

so how do equivalent add jar using sparklyr?

edit: tried this:

spark_dependencies <- function(spark_version, scala_version, ...) {   sparklyr::spark_dependency(     jars = c(       system.file(         sprintf("/usr/hdp/2.4.2.0-258/hive/lib/json-serde-1.3.7-jar-with-dependencies.jar"),     package = "jsonserde"       )     )   ) } .onload <- function(libname, pkgname) {   sparklyr::register_extension(pkgname) }  library(jsonserde)

but still same error , library(jsonserde) gives:

error in library(jsonserde) : there no package called ‘jsonserde’

i see nothing in spark log adding dependency.

the issue not sparklyr one: setting in tez.lib.uris. changed to:

/hdp/apps/${hdp.version}/tez/tez.tar.gz,hdfs://master.royble.co.uk:8020/jars/json-serde-1.3.7-jar-with-dependencies.jar

(note: no space after comma , hdfs path). issue of:

error in library(jsonserde) : there no package called ‘jsonserde’

still stands , accept answer that.
