hadoop - Error while using Revolution R to convert a csv file to an xdf using rxImport function -


i trying take csv file cloudera , convert xdf

i have tried following:

inputfile <- file.path("/user/...")  #create column classes data set columnclasses <- c("character", "character", "character",                     "character", "character", "character",                     "character", "character", "character",                     "character", "character", "numeric", "character"                    )  names(columnclasses) <- paste("v", seq(1:13), sep = "")  ##convert input csv file rxtextdata object textdata <- rxtextdata(file = inputfile,                          filesystem = hdfsfs,                          colclasses = columnclasses                          )  ##set chunk size chunk.size <- 250000  ##create output file location newxdf <- rxxdfdata("/user/...", filesystem = hdfsfs)  rximport(indata = inputfile,      outdata = newxdf,      rowsperread = chunk.size,      overwrite = true,      numrows = -1)

when run following error:

error in rxuhandleclusterjobtryfailure(retobject, hpcserverjob, autocleanup,  :    error completing job on cluster: error in rxexecindatahadoop(callinfo, matchcall) :    data source not have hdfs file system type.

note: have looked @ textdata using functions rxgetinfo , looks fine.

any insights why i'm getting error?

update: typo in rximport function.

actually ran:

rximport(indata = textdata,      outdata = newxdf,      rowsperread = chunk.size,      overwrite = true,      numrows = -1)

and got following error:

error in rxuhandleclusterjobtryfailure(retobject, hpcserverjob, autocleanup,  :    error completing job on cluster: error in rxcall("rx_importdatasource", params) :
