Hi
When I installed Zeppelin, I created a zeppelin user with below
permission:uid=500(zeppelin) gid=490(hdfs)
groups=490(hdfs),492(hadoop),501(supergroup)
I ran this via pyspark just fine under this zeppelin user
myfile =
sc.textFile("hdfs://cdhe1master.fbdl.local:8020/user/zeppelin/testcdh.log")lineLengths
= myfile.map(lambda s: len(s))totalLength = lineLengths.reduce(lambda a, b: a
+ b)
print totalLength
However, when I run the same thing using Zeppelin, I got this error below. Any
idea?
