[jira] [Commented] (DRILL-1816) Scan Error with JSON on large no of records with Complex Types

["Daniel Barclay (Drill) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/DRILL-1816?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14522053#comment-14522053 ] 

Daniel Barclay (Drill) commented on DRILL-1816:
-----------------------------------------------

Investigation note:

Hmm.  Something about this is intermittent or state-dependent:

A first try at reproducing this consistently returned wrong numbers of rows (around 15,000 rather than 100,000).

However, subsequent tries returned the correct number of rows.
