issue with hdfs.line.reader function which only returns the function itself

[chelsea]

I'm running the following line and it only returns the function itself. Does anyone have any idea why it happens? Thanks!

l <- hdfs.read.text.file("/user/ychen/id.csv")

> l

$read

function (nl = n) 

{

    .jcall(f, "[Ljava/lang/String;", "getLines", as.integer(nl))

}

<environment: 0x39a81a8>

$close

function () 

{

    .jcall(f, "V", "close")

}

<environment: 0x39a81a8>
