Eric O. LEBIGOT (EOL) updated SPARK-7141:
-----------------------------------------
Description:
Using {{saveAsTextFile("s3://bucket/prefix"}} actually adds an empty prefix,
i.e. it writes to {{s3://bucket//prefix}} (note the double slash).
Example code (in a {{pyspark}} shell):
{{rdd = sc.parallelize("abcd")}}
{{rdd.saveAsTextFile("s3://bucket/prefix")})
This is quite annoying, as the files cannot be saved in the intended location
(they can be read, though, with the original path:
{{sc.textFile("s3://bucket/prefix"}}, but the AWS console does not show them in
the right place).
Also, many `block_` files are created directly in the bucket: shouldn't they be
deleted? (This may be a separate issue, but maybe it is a path issue as well.)
