  • Article assumes that you have a setup of Ubuntu/CentOS server
  • Access to Ubuntu/CentOS repository
  • Have libsasl2-modules-gssapi-mit installed
  • Have "gcc" installed, required for compilation when building from source
  • Have "make" installed, required for compilation when building from source
  • Verify if you have a working Ubuntu repository by typing "sudo apt-get update" and see if this returns successfully
  • Within CentOS as a non superuser you can run "sudo yum repolist" wherein the "base" and "epel" repositories should get listed with thousands as value in "status" field
  • Here are the examples of working repository on either systems
  • This node should be able to talk to the HiveServer2 via hostname/IP address

Installing UnixODBC on Ubuntu

  • Using existing repository

  • Using source file, which can be downloaded HERE. This is good if you want a custom version of the driver and a custom location for the binaries and libraries to be installed
    • Make a directory where you want to have the files downloaded for e.g., "/opt/odbc/unixodbc"
    • Change path to this directory "cd /opt/odbc"
    • Download the file in this location
    root@srai-odbc-ubuntu:~/ODBC# wget

    • Extract the files from the tarzip file
root@srai-odbc-ubuntu:~/ODBC# tar -xzf unixODBC-2.3.4.tar.gz
  • After the tarzip file has been extracted, you should be able to change directory to that folder
cd unixODBC-2.3.4
  • By default when you build the source, files are copied within /usr/local/bin, /usr/local and /usr/local/man. Run the following, assuming you want the installation to be performed in a different location, for instance "/opt/odbc/unixodbc"
./configure --prefix=/opt/odbc/unixodbc --exec-prefix=/opt/odbc/unixodbc/oth --bindir=/opt/odbc/unixodbc/bin --sbindir=/opt/odbc/unixodbc/sbin --libexecdir=/opt/odbc/unixodbc/libexec --sysconfdir=/opt/odbc/unixodbc/etc --libdir=/opt/odbc/unixodbc/lib --includedir=/lib --includedir=/lib64
make install 
  • Once the installation is complete, you should be able to find the "isql" binary
# find /usr/local -name isql
  • Execute the command "odbcinst -j", this should return the location of configuration files
# cd /opt/odbc/unixodbc/bin
# ./odbcinst -j

NOTE: If you see this error

/usr/local/bin/odbcinst: error while loading shared libraries: cannot open shared object file: No such file or directory

..this can be due to libraries not being found, but they might exist on the system. Perform the following steps to verify and fix this

# ldd /opt/odbc/unixodbc/odbcinst =>  (0x00007fff33dfe000) => not found => /lib/x86_64-linux-gnu/ (0x00007f7f739e2000) => /lib/x86_64-linux-gnu/ (0x00007f7f7361c000) => /lib/x86_64-linux-gnu/ (0x00007f7f73418000)

Installing & Configure Hive ODBC on Ubuntu

  • Download the driver HERE
  • Copy the driver over to any temporary/staging directory or to a directory where you conserve all the binaries, for e.g., "/opt/odbc"
  • Install the driver package using the following command
# dpkg -i hive-odbc-native_2.1.2.1002-2_amd64.deb
(Reading database ... 54835 files and directories currently installed.)
Preparing to unpack hive-odbc-native_2.1.2.1002-2_amd64.deb ...
Unpacking hive-odbc-native ( over ( ...
Setting up hive-odbc-native ( ...
  • Ensure that the libraries installed (if UnixODBC was installed from source files) are included in LD_LIBRARY_PATH
export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/lib:/lib64:/opt/odbc/unixodbc/lib
  • Locate the files "odbc.ini" and "odbcinst.ini", location based on your method of installation. By default the files are available under /etc/, however, it can also be present in /usr/local/etc. In our case, assuming the custom installation, the files will be available under /opt/odbc/unixodbc/etc
root@srai-odbc-ubuntu:/opt/odbc/unixodbc/etc# ls -lrth /opt/odbc/unixodbc/etc
total 4.0K
-rw-r--r-- 1 root root    0 Aug 25 18:00 odbcinst.ini
-rw-r--r-- 1 root root    0 Aug 25 18:00 odbc.ini
drwxr-xr-x 2 root root 4.0K Aug 25 18:00 ODBCDataSources
  • Copy the files from hive installation directory into this location
# cp /usr/lib/hive/lib/native/hiveodbc/Setup/odbc.ini /opt/odbc/unixodbc/etc/odbc.ini
# cp /usr/lib/hive/lib/native/hiveodbc/Setup/odbcinst.ini /opt/odbc/unixodbc/etc/odbcinst.ini
  • Edit the file using vi or other editor and configure the following
    • locate the string "[Sample Hortonworks Hive DSN 64]" this is the DSN, short for Data Source Name. You can change it to anything you like, for instance "hivedb"
    • Ensure that the variable HOST has the name for HiveServer2
    • PORT by default should be set to 10000, or as configured otherwise
    • AuthMech should be set to 0 for no authentication OR 1 for Kerberos
    • UID can be set to hive or as needed
    • KrbHostFQDN should be the FQDN of Kerberos Server
    • KrbServiceName should be the principal name configured for hive OR the principal created
    • KrbRealm should be the name of realm, for instance EXAMPLE.COM

Here is the sample configuration output

  • Export the variables to ensure that only our configured configuration files are being used
export ODBCINI=/opt/odbc/unixodbc/odbc.ini
export ODBCSYSINI=/opt/odbc/unixodbc
export HORTONWORKSHIVEINI=/usr/lib/hive/lib/native/Linux-amd64-64/hortonworks.hiveodbc.ini
  • Ensure that hortonworks.hiveodbc.ini (as stated above) is pointing to the correct ODBC library, in here since we are using UnixODBC manager + Hive ODBC driver (Simba), we need to comment out the default "" and uncomment ""
# Generic ODBCInstLib
#   iODBC  <<<<<<< Comment This
#   SimbaDM / unixODBC <<<<<<< Uncomment

Testing the connectivity

  • Get the ticket from Hive and Kerberos using keytab file. In this case, is the host which serves HiveServer2 connectivity
# kinit -k -t /tmp/hive.service.keytab hive/
# klist
  • Once the ticket is granted, execute the following command to test connectivity
# /opt/odbc/unixodbc/bin/isql hivedb -v
  • You can run some commands to verify if you are able to list the database and access the table data.
# /opt/odbc/unixodbc/bin/isql hivedb

The process of installing UnixODBC on CentOS precisely the same with the exception of how firewalls are turned off. Everything else is virtually the same.

Enabling Debug Logging

  • Open the file "hortonworks.hiveodbc.ini", you can use either of the following methods
# vi /usr/lib/hive/lib/native/Linux-amd64-64/hortonworks.hiveodbc.ini
  • The only two parameters that we need to modify are "LogLevel" and "LogPath", here are the examples. Zero is basically no logging.
  • Once the variables are set, run a few commands and see that there will be two log files generated within the LogPath specified above. These files can be reviewed for debugging information.
