Error in function hdfs.cmd with rmr2 version 3.2.0

[koje]

Hi,

i got an error in the hdfs.cmd function with the new rmr2 version 3.2.0.
This is the error text:
Fehler in if (file.exists(cmd)) return(cmd) : Argument hat Länge 0

The following command produces a 0-length vector, therefore the error above occurs. I use on my system hadoop version 1.2.1 where no hdfs file in the hadoop bin directory exists.

suppressWarnings( system2( command = "which", args = "hdfs", stdout = TRUE, stderr = FALSE))}

It would be nice if you could fix it.

Regards, koje

Sorry about that and thanks for the accurate analysis. As a workaround you
can set the environment variable HDFS_CMD.

If you have a chance to try it out and report back I would appreciate it (I had a hard time actually reproducing this)

I faced the same issue. The code changed worked.
