[jira] [Created] (MAPREDUCE-4498) Downgrade hsqldb dependency to
1.8
Robert Kanter created MAPREDUCE-4498:
----------------------------------------
Summary: Downgrade hsqldb dependency to 1.8
Key: MAPREDUCE-4498
URL: https://issues.apache.org/jira/browse/MAPREDUCE-4498
Project: Hadoop Map/Reduce
Issue Type: Bug
Components: build, examples
Affects Versions: 2.2.0-alpha
Reporter: Robert Kanter
Assignee: Robert Kanter
Priority: Critical
Fix For: 2.2.0-alpha
The hsqldb jar is included in hadoop for the DBCountPageView example only. Currently the example is using hsqldb version 2.x; however, 2.x is incompatible with 1.8.x -- having this jar in the hadoop class path conflicts with dependent projects like Oozie, Hive, and Pig which still use 1.8.x. As there are no features hsqldb 2.x that are used by the example, we should downgrade to 1.8.x to avoid conflicts for the other projects.

[jira] [Updated] (MAPREDUCE-4498) Remove hsqldb jar from Hadoop

Attachment: MAPREDUCE-4498-v3.patch
The TestCombineFileInputFormat test fails even without the patch; so it seems to be unrelated.

[jira] [Updated] (MAPREDUCE-4498) Remove hsqldb jar from Hadoop
runtime classpath
Posted by "Robert Kanter (JIRA)" <ji...@apache.org>.

Robert Kanter updated MAPREDUCE-4498:
-------------------------------------
Attachment: MAPREDUCE-4498-v2.patch
Alejandro and I tried to modify the example to use reflection to pick up the hsql jar from the -libjars argument, but that just caused it to fail in the DBInputFormat because DriverManager tries to instantiate the JDBC driver from the bootstrap classloader (-libjars is a different classloader). This approach also made the example's code unnecessarily complicated because of all of the reflection.
Instead, we left the example's code alone, but moved the hsqldb 2.x jar out of the mapred/lib/ dir of the TAR and into a new mapred/lib-examples/ dir. Then to run the DBCountPageView example, you would do:
{noformat}
$ export HADOOP_CLASSPATH=share/hadoop/mapreduce/lib-examples/hsqldb-2.0.0.jar
$ bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-3.0.0-SNAPSHOT.jar dbcount -libjars share/hadoop/mapreduce/lib-examples/hsqldb-2.0.0.jar
{noformat}

[jira] [Commented] (MAPREDUCE-4498) Downgrade hsqldb dependency to
1.8
Posted by "Alejandro Abdelnur (JIRA)" <ji...@apache.org>.

Alejandro Abdelnur commented on MAPREDUCE-4498:
-----------------------------------------------
It seems it is not that simple. The DBCountPageView example starts/shutdowns HSQLDB server if the driver is for HSQLDB. This means that the HSQLDB JAR must be in the bootstrap classloader. A way to address this is to do all the start/shutdown of HSQL via reflection in the context of the *Thread.currentThread().getContextClassLoader()* classloader.

+1. Is there any objection to this approach?
Also, Robert would you look if there is any doc/wiki that explains how to run the dbcount example? We would need to update this as well.

------------------------------------------
The only documentation I could find is in the javadoc comments for the DBCountPageView and the printout when you run the examples jar without specifying which example. I'll update the patch to add the instructions on how to run dbcount.

> The hsqldb jar is included in hadoop for the DBCountPageView example only. Currently the example is using hsqldb version 2.x; however, 2.x is incompatible with 1.8.x -- having this jar in the hadoop class path conflicts with dependent projects like Oozie, Hive, and Pig which still use 1.8.x. As there are no features hsqldb 2.x that are used by the example, we should remove it from Hadoop's runtime classpath.

---------------------------------------------
+1 to Alejandro's suggestions. Keeping hadoop's classpath to absolute minimum will avoid headaches for all the downstream projects. I have been hit by this more then once.

Why don't we update the example to show how to add HSQL to the classpath instead of forcing HSQL on everyone? You can add it in with an environment variable very easily.

Actually I believe it was specifically upgraded to 2.X to fix a bug in the tests - see MAPREDUCE-3621. So if you do this I want to make sure thoses tests don't start failing.
