Hyunsik Choi commented on TAJO-649:
-----------------------------------
Hi Guo,
Yes, Tajo provides the JDBC driver. Although the JDBC driver needs more tests,
it works well in most cases.
You can get Tajo JDBC driver as follows:
{noformat}
$ cd ${TAJO_ROOT}
$ mvn clean package -Pdist -Dtar -DskipTests
$ ls -l ${TAJO_ROOT}/tajo-dist/target/tajo-0.8.0-SNAPSHOT/share/jdbc-dist/
{noformat}
The directory jdbc-dist contains several jar files. In order to use this JDBC
driver, you should include the jar files in jdbc-dist as well as the output of
'hadoop classpath'.
As you already know, '${HADOOP_HOME}/bin/hadoop classpath' command outputs the
following CLASSPATH:
{noformat}
hyunsik@Hyunsiks-MacBook-Pro:hadoop-2.2.0$ bin/hadoop classpath
/Users/hyunsik/Code/hadoop-2.2.0/etc/hadoop:/Users/hyunsik/Code/hadoop-2.2.0/share/hadoop/common/lib/*:/Users/hyunsik/Code/hadoop-2.2.0/share/hadoop/common/*:/Users/hyunsik/Code/hadoop-2.2.0/share/hadoop/hdfs:/Users/hyunsik/Code/hadoop-2.2.0/share/hadoop/hdfs/lib/*:/Users/hyunsik/Code/hadoop-2.2.0/share/hadoop/hdfs/*:/Users/hyunsik/Code/hadoop-2.2.0/share/hadoop/yarn/lib/*:/Users/hyunsik/Code/hadoop-2.2.0/share/hadoop/yarn/*:/Users/hyunsik/Code/hadoop-2.2.0/share/hadoop/mapreduce/lib/*:/Users/hyunsik/Code/hadoop-2.2.0/share/hadoop/mapreduce/*:/Users/hyunsik/Code/hadoop-2.2.0/contrib/capacity-scheduler/*.jar
{noformat}
If you want to use smaller jar files, please refer this article
(http://www.jaso.co.kr/491). Although this article is written in Korean, you
can see the list of jar files. The author tried to use Tajo JDBC driver for R,
which is a statistical computing framework. In his article, he showed only
necessary JAR files.
In addition, I would like to suggest you to subscribe and use the user mailing
list ([email protected]) for Q&A because Jira has been used for
development issues :) Please see this page
(http://tajo.incubator.apache.org/mailing-lists.html) for more information of
mailing list.
Regards,
Hyunsik
