我正在运行这段代码
b.time <- proc.time()
small.ints= to.dfs(1:9000000)
result = mapreduce(input = small.ints, map = function(k,v) cbind(v,v^2))
两个月前运行此代码时,它运行良好。 但是现在运行它会出现错误
Error in mr(map = map, reduce = reduce, combine = combine,
vectorized.reduce, :
hadoop streaming failed with error code 1
18/07/19 22:40:02 INFO fs.TrashPolicyDefault: Namenode trash configuration:
Deletion interval = 0 minutes, Emptier interval = 0 minutes.
我该怎么办?
我认为这很容易出错,但是我是hadoop和ubuntu的初学者,所以我自己解决的能力很少。请告诉我详细信息
