Summary: select * fails on a text file with 3500 columns or more
Key: DRILL-1958
URL: https://issues.apache.org/jira/browse/DRILL-1958
Project: Apache Drill
Issue Type: Bug
Components: Storage - Text & CSV
Reporter: Rahul Challapalli
Assignee: Hanifi Gunes
git.commit.id.abbrev=b491cdb
The dataset contains a single record with 3500 columns. 'select *' returns an
empty set. However with 3000 columns 'select *' has no issues.
Selecting an individual columns worked with both the data sets. Also json does
not seem to have this problem
{code}
0: jdbc:drill:schema=dfs.wide-columns> select * from `temp.tsv`;

No rows selected (0.174 seconds)
0: jdbc:drill:schema=dfs.wide-columns> select columns[0] from `temp.tsv`;

| 4788998.32516 |
+------------+
1 row selected (0.244 seconds)
{code}
There was no activity in the log files when the select * did not return
anything. I attached the data file
