Re: Dataset : Issue with Save
Looks like the current fix is reducing accumulator data being sent to driver,
but there are still lots of more statistics data being sent to the driver. It
is arguable that how much data is reasonable for 3.7k tasks.
You can attach your heap dump file in that JIRA and follow it.

Subject: Re: Dataset : Issue with Save
I am using SPARK 2.0 . There are comments in the ticket since Oct-2016 which
clearly mention that issue still persists even in 2.0.
I agree 1G is very small today's world, and I have already resolved by
increasing the spark.driver.maxResultSize.
I was more intrigued as to why is the data being sent to driver during
save(similat to collect() action ), are there any plans to fix this
behavior/issue ?
Thanks,

First, you didn't tell us what version of your Spark you are using. The JIRA
clearly said that it is a bug in Spark 1.x, and should be fixed in Spark 2.0.
So help yourself and the community, to confirm if this is the case.
If you are looking for workaround, the JIRA ticket clearly show you how to
increase your driver heap. 1G in today's world really is kind of small.

Hi,
Was this not yet resolved?
Its a very common requirement to save a dataframe, is there a better way to
save a dataframe by avoiding data being sent to driver?.
"Total size of serialized results of 3722 tasks (1024.0 MB) is bigger than
spark.driver.maxResultSize (1024.0 MB) "

Spark driver requires large memory space for serialized

Executing a sql statement with a large number of partitions requires a high

the driver.

Hi,
While saving a dataset usingmydataset.write().csv("outputlocation")
I am running into an exception
"Total size of serialized results of 3722 tasks (1024.0 MB) is bigger than
spark.driver.maxResultSize (1024.0 MB)"
Does it mean that for saving a dataset whole of the dataset contents are being
sent to driver ,similar to collect() action?
Thanks,
Baahu
