Date Sat, 20 Jun 2015 01:17:00 GMT

Rahul Challapalli updated DRILL-3328:
-------------------------------------
    Description: 
git.commit.id.abbrev=710f829

The below query fails with a fragment initialization error

{code}
select cast(col1 as varchar(10)) from hive.temp_bin;
Error: PARSE ERROR: From line 1, column 8 to line 1, column 32: Cast function cannot convert
value of type BINARY(1) to type VARCHAR(10)


[Error Id: e7937c82-a249-4596-895f-eae2c54cfd45 on qa-node191.qa.lab:31010] (state=,code=0)
{code}

Data creation steps :
{code}
create table temp_bin (col1 BINARY) STORED AS TEXTFILE;
insert overwrite table temp_bin select encode('abc', 'UTF-8') from temp limit 1;
{code}


I attached the error logs.

  was:
git.commit.id.abbrev=710f829

The below query fails with a fragment initialization error

{code}
select convert_from(col1, 'UTF-8') from temp_bin;
Error: SYSTEM ERROR: org.apache.drill.exec.work.foreman.ForemanException: Unexpected exception
during fragment initialization: null

{code}

Data creation steps :
{code}
create table temp_bin (col1 BINARY) STORED AS TEXTFILE;
insert overwrite table temp_bin select encode('abc', 'UTF-8') from temp limit 1;
{code}
