             Summary: Parquet file created from impala using data from an impala table causes drill to hang
                 Key: DRILL-817
                 URL: https://issues.apache.org/jira/browse/DRILL-817
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Norris Lee


A normal table was created with impala:
{code}
[localhost.localdomain:21000] > create table integer_table2 (keycolumn string, column1 int) row format delimited fields terminated by ',';
Query: create table integer_table2 (keycolumn string, column1 int) row format delimited fields terminated by ','

Returned 0 row(s) in 0.10s
[localhost.localdomain:21000] > show tables;
Query: show tables
+-----------------------+
| name                  |
+-----------------------+
| integer_table2        |
+-----------------------+
Returned 1 row(s) in 0.01s
{code}

Data from a csv is loaded into the table
{code}
46:44 PDT 2014)
[localhost.localdomain:21000] > load data inpath '/user/hive/warehouse/Integer_Table.csv' overwrite into table integer_table2;
Query: load data inpath '/user/hive/warehouse/Integer_Table.csv' overwrite into table integer_table2
+----------------------------------------------------------+
| summary                                                  |
+----------------------------------------------------------+
| Loaded 1 file(s). Total files in destination location: 1 |
+----------------------------------------------------------+
Returned 1 row(s) in 0.23s
{code}

A parquet table was then created in impala and data loaded in from the first table:
{code}
[localhost.localdomain:21000] > create table integer_table (keycolumn string, column1 int) row format delimited fields terminated by ',' stored as parquet;
Query: create table integer_table (keycolumn string, column1 int) row format delimited fields terminated by ',' stored as parquet

Returned 0 row(s) in 0.10s
[localhost.localdomain:21000] > insert overwrite table integer_table select * from integer_table2;
Query: insert overwrite table integer_table select * from integer_table2
Inserted 18 rows in 0.20s
{code}

The parquet file (in the format <long alphanumeric string>_data.0 and renamed) was extracted from hdfs and moved to drill's dfs. The query through sqlline hangs:
{code}
0: jdbc:drill:schema=hivestg> select * from `dfs`.`/opt/drill/integer.parquet`;
<hang>
{code}
