Eli Collins updated HDFS-613:
-----------------------------
Affects Version/s: (was: 0.21.0)
0.22.0
Fix Version/s: 0.22.0
They're on by default now. I didn't see this one when enabling asserts in hdfs
because in the tests it gets reported as a junit assertion error instead of a
java.lang one:
Mismatched number of datanodes
junit.framework.AssertionFailedError: Mismatched number of datanodes
Here's the assert that's firing:
{noformat}
assert (datanodes.size() ==
overUtilizedDatanodes.size()+underUtilizedDatanodes.size()+
aboveAvgUtilizedDatanodes.size()+belowAvgUtilizedDatanodes.size()+
sources.size()+targets.size())
: "Mismatched number of datanodes";
{noformat}
> TestBalancer fails with -ea option.

> Key: HDFS-613
> URL: https://issues.apache.org/jira/browse/HDFS-613
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: test
> Affects Versions: 0.22.0
> Reporter: Konstantin Shvachko
> Fix For: 0.22.0
>
>
> Running TestBalancer with asserts on. The asserts in
> {{Balancer.chooseNode()}} is triggered and the test fails. We do not see it
> in the builds because asserts are off there. So either the assert is
> irrelevant or there is another bug in the Balancer code.
