[jira] [Commented] (DRILL-1953) alter session set `store.json.all_text_mode` does not work as documented

    [ https://issues.apache.org/jira/browse/DRILL-1953?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14297243#comment-14297243 ] 

Deneche A. Hakim commented on DRILL-1953:
-----------------------------------------

Looking at the source code, the problem seems located in JSONRecordReader's constructor, the following line uses a {{SystemOptionManager}} to fetch the value of the option:
{code}
    this.enableAllTextMode = fragmentContext.getDrillbitContext().getOptionManager().getOption(ExecConstants.JSON_ALL_TEXT_MODE).bool_val;
{code}
