I'm trying to query data from a Hive table on a MapR platform. My query is:

use Modern::Perl;
use DBI;
use Data::Dumper;

my $dbh = DBI->connect('dbi:ODBC:DSN=myDSN', undef, undef, {RaiseError
+ => 1});
$dbh->{LongReadLen} = 1000000; 
$dbh->{LongTruncOk} = 1;


my $sth = $dbh->prepare(q{select * from table});
$sth->execute;

while (my $row = $sth->fetchall_arrayref) {
    say Dumper $row;
}

What I get is the following line repeated hundreds of times to STDERR

DBD::ODBC::st fetchall_arrayref warning: no select statement currently
+ executing
 at conn.pl line 17.

Then I get the one row in the table, followed by a never-ending stream of the following to STDOUT

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

$VAR1 = [];

And the following to STDERR

DBD::ODBC::st fetchall_arrayref warning: no select statement currently
+ executing
 at conn.pl line 17.
DBD::ODBC::st fetchall_arrayref warning: no select statement currently
+ executing
 at conn.pl line 17.
DBD::ODBC::st fetchall_arrayref warning: no select statement currently
+ executing
 at conn.pl line 17.
DBD::ODBC::st fetchall_arrayref warning: no select statement currently

DBD::ODBC::st fetchall_arrayref warning: no select statement currently

DBD::ODBC::st fetchall_arrayref warning: no select statement currently

DBD::ODBC::st fetchall_arrayref warning: no select statement currently
+ executing
 at conn.pl line 17.
DBD::ODBC::st fetchall_arrayref warning: no select statement currently
+ executing
 ... repeat forever ....

I have to Control-C to stop this. Any explanation and way forward is appreciated
