rhive.exportAll('scorint') Error in RSeval(rcon, command) : remote evaluation failed In addition: Warning messages: 1: In readBin(c, "int", 4, signed = FALSE, endian = "little") : 'signed = FALSE' is only valid for integers of sizes 1 and 2 2: In readBin(c, "int", 4, signed = FALSE, endian = "little") : 'signed = FALSE' is only valid for integers of sizes 1 and 2

I find the resolution about this problem: that because I haven't create the RHIVE_DATA directory and grant 777 to it. it should restart the Rserve on every node of cluster for reread the configuration include RHIVE_DATA.
