[jira] [Updated] (SPARK-16070) DataFrame/Parquet issues with
primitive arrays
[ https://issues.apache.org/jira/browse/SPARK-16070?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
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
* Not sufficient array size checks ([NegativeArraySizeException](https://issues.apache.org/jira/issues/?jql=project%20%3D%20SPARK%20AND%20text%20~%20NegativeArraySizeException) or silent errors)
** There
* Performance of Parquet encodings on saving primitive arrays
