Question about connecting to Hadoop.

$

Hi,

 

Env) Hadoop and IQ are separated from each other on other host.

1) CentOS 7 + Apache Hadoop 2.7.0 + Apache Hive 1.2 + Thrift hiveserver2

2) IQ16 SP08 PL32 + unixODBC 2.3.1 + Hortonworks Hive ODBC 2.2

 

I already unlink the IQ driver manager with white paper.

When I try to connect to Hadoop, The following error is returned.

 

(DBA)> create server hive_test class 'ODBC' using 'dsn=hive'

Execution time: 0.003 seconds

 

(DBA)> forward to hive_test

0 row(s) affected

Execution time: 0.001 seconds

 

(DBA)> select * from testTable

Could not execute statement.

  Unable to connect to server 'hive_test': [unixODBC][

SQLCODE=-656, ODBC 3 State="HY000"

  Line 1, column 1

  select * from testTable

Press ENTER to continue...

 

Table(testable) is stored in HDFS.

 

[iq16@CentOS ~]$ /usr/bin/isql -v hive

SQL> select * from testTable;

+------------+---------+---------------------------------+

| num        | ename   | kname |

+------------+---------+---------------------------------+

| 1          | tom     | xxx |

| 2          | jack    | xxx |

| 3          | july    | jjj |

+------------+---------+---------------------------------+

 

Here are ODBC INFO:

 

[hive]

Driver=/usr/lib/hive/lib/native/Linux-amd64-64/libhortonworkshiveodbc64.so

HOST=localhost

PORT=10000

Schema=default

HiveServerType=2

HS2AuthMech=2

UserName=hive

UID=hive

PWD=

 

[iq16]

uid=dba

pwd=sql

eng=insung_iqdemo

dbn=iqdemo

commlinks=tcpip{host=localhost;port=2638}

Driver=/home/hadoop/iq16_sp08_pl32/IQ-16_0/lib64/libdbodbc16.so

 

Here are what I did.

  1. Localhost -> IP,Hostname in odbc
  2. Added the odbc and LIBPATH in .bash_profile
    Ex) export LIBPATH="/home/iq16/IQ-16_0/lib64"

export ODBCINI="/home/iq16/odbc.ini"

   3. Unlink the IQ odbc driver manager

   4. Set LANG=C

Any comments and advice will be appreciated.
