Subject [jira] Commented: (HIVE-1129) Assertion in ExecDriver.execute when assertions are enabled in HADOOP_OPTS
Date Thu, 04 Feb 2010 20:21:29 GMT


John Sichi commented on HIVE-1129:

In the spirit of keeping patch transactions small and focused, maybe it would be better to
commit this patch as is and assign me a separate JIRA for adding and using the setter methods?
 The reason I say this is that my patch followed the existing pattern here in the same file:

    if(work.getMinSplitSize() != null) {

So that code will need to be changed too as part of consistently using the new setters, and
that change is unrelated to my fix for the existing bug with assertions.

> I noticed that when running hive CLI, assertions are not enabled, which was causing me
some confusion when debugging an issue.
> So, I added the following to my environment:
> export HADOOP_OPTS="-ea -esa"
> This worked, and allowed me to see assertion failures when executing via CLI.
> But then I tried to run a test, and got an assertion failure from the following code
in ExecDriver.execute:
>     // Turn on speculative execution for reducers
>     HiveConf.setVar(job, HiveConf.ConfVars.HADOOPSPECULATIVEEXECREDUCERS,
>         HiveConf.getVar(job, HiveConf.ConfVars.HIVESPECULATIVEEXECREDUCERS));
> The assertion says it should be using getBoolVar/setBoolVar instead.
