Xiangrui Meng updated SPARK-16070:
----------------------------------
Description:
I created this umbrella JIRA to track DataFrame/Parquet issues with primitive
arrays. This is mostly related to machine learning use cases, where feature
indices/values are stored as (usually large) primitive arrays.
Issues:
* SPARK-16043: Tungsten array data is not specialized for primitive types
* SPARK-16071: Not sufficient array size checks
([NegativeArraySizeException|https://issues.apache.org/jira/issues/?jql=project%20%3D%20SPARK%20AND%20text%20~%20NegativeArraySizeException]
or silent errors)
* SPARK-16073: Performance of Parquet encodings on saving primitive arrays
