-------------------------------------
This failure is super-goofy. My hunch is it's something to do with non-threadsafe use of classloaders or some other bad synchronization, but I don't have much to go on. Any ideas?

[jira] [Updated] (HADOOP-8157)
TestRPCCallBenchmark#testBenchmarkWithWritable fails with RTE
Posted by "Todd Lipcon (Updated) (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HADOOP-8157?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Todd Lipcon updated HADOOP-8157:
--------------------------------
Attachment: hadoop-8157.txt
I believe the problem is this:
The cache added by HADOOP-6502 used a "null" value in the map as a negative cache entry for a class not found. However, it uses a WeakHashMap to avoid leaking references. The semantics of WeakHashMap are such that we could hit the following scenario:
- check "containsKey()" for a given key, see it was there
- GC runs and clears that key from the map
- call "get" and return null.
- Now we think it was a negative cache entry and throw ClassNotFoundException
The fix here is to stop using nulls to cache the "not found" result. Instead, we insert a special sentinel value as a negative cache entry.
Unfortunately it's diffcult to reproduce this on my box, but we've seen TestRPCCallBenchmark fail on Hudson a lot without this patch. So if we commit this, and we stop seeing the failures, we'll know we fixed the bug.

I think I understand this bug. It's probably due to an error in HADOOP-6502. Patch and explanation en route.
