[jira] [Commented] (DRILL-2567) CONVERT_FROM in where clause - Error.

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

    [ https://issues.apache.org/jira/browse/DRILL-2567?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14380859#comment-14380859 ] 

Aditya Kishore commented on DRILL-2567:
---------------------------------------

The issue is that Unpooled.wrappedBuffer() sets the writeIndex == capacity. This must be rewound to 0 before writing the data into it.
