[jira] [Commented] (SPARK-12679) Collect method return empty rows.

["Sasi (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/SPARK-12679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15086204#comment-15086204 ] 

Sasi commented on SPARK-12679:
------------------------------

Scenario that I can explains is:
1)	Aerospike table is full with data.
2)	Create temporary table with the same data I have in Aerospike.
3)	Do query such as “select * from tmpTable” and getting the same results. (Array of rows equals by the size of Aerospike data)
4)	Iterate on each row and get NULL as a content.

> Hi,
> I don't know where to put my fingre on that issue, on the connector or on Spark, but sometimes when I do SQL query I get empty rows.
> Example code:
>      rows = Arrays.asList(sparkCtx.sparkSql(“select * from tmpTable”).collect());
>       iterate Row row -> rows
> system-out(row.getString(0)) -----return null
> I tried to find open bugs on the collect method, without any luck.
