[jira] [Commented] (DRILL-1954) Update CSV Writer to treat a single RepeatedVarChar column as separate columns on output rather than Erroring

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

    [ https://issues.apache.org/jira/browse/DRILL-1954?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14269475#comment-14269475 ] 

Jacques Nadeau commented on DRILL-1954:
---------------------------------------

I just ran across this recently as well.  Drill's text/csv representation when reading is a repeated varchar but output is expected to be delineated columns.  We should really have better handling so that a single repeated varchar output is also a handled correctly in CSV.  

An ugly work around for now if doing a ctas on the individual columns.  For example: 

CREATE TABLE fcc_cell AS select columns[0], columns[1], columns[2], columns[3], ..., columns[n]  from dfs.`/Users/Documents/fcc/fcc_lic_vw.csv` WHERE columns[10] IN ('"Mobile/Fixed Broadband"', '"Fixed Wireless"') AND columns[17] = '"A"';
