rhbase hb.insert.data.frame error

[该走了]

Hi, everyone I am new to use rhbase, and I met some problem, I try to run a simple example from rhbase like

library(rhbase)
hb.init()
hb.new.table('testtable','x','y','z')
hb.describe.table('testtable')
# Not required to labels to be 'family:label', can just provide 'family'
# which is equivalent to 'family:'
hb.insert("testtable",list(list("20100101",c("x:a","x:f","y","y:w"), list("James Dewey",TRUE, 187.5,189000))))
hb.insert("testtable",list(list("20100102",c("x:a"), list("James Agnew"))))
hb.insert("testtable",list(list("20100103",c("y:a","y:w"), list("Dilbert Ashford",250000))))
hb.insert("testtable",list(list("20100104",c("x:f"), list("Henry Higs"))))


hb.get("testtable",list("20100101","20100102"))
hb.get("testtable",list("20100101","20100102"),c("y")) # columns that start with y
hb.get("testtable",list("20100101","20100102"),c("y:w"))
hb.get("testtable",list("20100101","20100102"),c("y:w","z"))


# delete
hb.delete("testtable","20100103","y:a")
hb.get("testtable","20100103")

## will not get 20100103, since no 'x'
iter <- hb.scan("testtable",startrow="20100100",colspec="x")
while( length(row <- iter$get(1))>0){
  print(row)
}
iter$close()

# scan from beginning
iter <- hb.scan("testtable",startrow="20100100",colspec=c('x','y','z'))
while( length(row <- iter$get(1))>0){
  print(row)
}
iter$close()

# scan uptil 20100103 (not including it)
iter <- hb.scan("testtable",startrow="20100100",end="20100103",colspec=c('x','y'))
while( length(row <- iter$get(1))>0){
  print(row)
}
iter$close()


# Insert a data frame
x <- data.frame(x=c("Winston","Jen","Jasmine"), y=runif(3),z=c(1,2,3))
rownames(x) <- c("20100105","20100106","20100107")
hb.insert.data.frame("testtable",x)

everything goes fine, but when I try to hb.insert.data.frame, I got an  error:

hb.insert.data.frame("testtable",x)
Error in hb.insert.data.frame("testtable", x) : 
  rhbase<addAndSendDFBatch>:: Internal error processing mutateRows

Is there any one know how to fix it, thanks in advance!

thrift 0.91
hbase 0.96

Not sure why you are seeing this error.  Can you run your test on a new hbase table instead of using 'testtable'
