I have a cloudera cluster with 3 hosts (one namenode and oterh two datanodes), and I installed Rstudio over Cloudera hadoop ecosystem by following the instruction:
However, I cannot check RStudio service use 'service rstudio-server status', it says 'rstudio-server: unrecognized service', anyone know why?
Also I cannot execute basic commands inside R like 'hdfs.ls(”/user/“)' and 'hdfs.cat(”/user/hdfs/o_same_school/part-m-00000″)', it shows errror by saying Error: object 'hdfs.cat' not found,
Besides, I tried 'library(rmr2)', It shows the error: 'Please review your hadoop settings. See help(hadoop.settings) Warning message: S3 methods ‘gorder.default’, ‘gorder.factor’, ‘gorder.data.frame’, ‘gorder.matrix’, ‘gorder.raw’ were declared in NAMESPACE but not found'
Please help me, thanks in advance.
