> support of reading ctrl-A delimited text file in storage-plugins.json
> ---------------------------------------------------------------------
>
> Key: DRILL-949
> URL: https://issues.apache.org/jira/browse/DRILL-949
> Project: Apache Drill
> Issue Type: Bug
> Reporter: Vivian Summers
> Assignee: Sudheesh Katkam
>
> Currently Drill doesn't support ctrl-A ('\001') type of delimiter in
> storage-plugins.json file:
> I have this in the format:
> "ctrlA" : {
> type: "text",
> extensions: [ "txt" ],
> delimiter: "\\001"
> },
> and getting error while Drillbit starts:
> Exception in thread "51a92118-3fab-4b4e-bdf9-2a7057ee52e4:frag:0:0"
> java.lang.IllegalArgumentException: Only single character delimiter supported
