able to avoid a shuffle when doing joins on tables that are already
bucketed by exposing more metastore information to the planner).
Can you provide more input on how to implement this functionality so that i

Hi all,
In my occasion, I have a huge HashMap[(Int, Long), (Double, Double,
Double)], say several GB to tens of GB, after each iteration, I need to
collect() this HashMap and perform some calculation, and then broadcast()
it to every node. Now I have 20GB for each executor and after it

enough memory?

Hi,
We have such requirements to save RDD output to HDFS with saveAsTextFile like
API, but need to overwrite the data if existed. I'm not sure if current Spark
support such kind of operations, or I need to check this manually?
There's a thread in mailing list discussed about this

I am wondering if we can provide more friendly API, other than configuration

So the behavior of overwriting existing directories IMO is something
we don't want to encourage. The reason why the Hadoop client has these
checks is that it's very easy for users to do unsafe things without
them. For instance, a user could overwrite an RDD that had 100
partitions with an RDD that
After a long talk with Patrick and TD (thanks guys), I opened the following
jira

Sample PR has an impementation for the batch and the dstream case, and a
link to a project with example usage.
