Uma Maheswara Rao G commented on HDFS-2452:
-------------------------------------------
Here is a patch with CountDownLatch.
Other changes in previous patch is:
1) fixed one null pointer, which is caused because of not mocking the getConf
on DN.
Added the mock in test.
2) DataXceiverAspects file apache header was not a header comment
{code}
+/*
+ * Licensed to the Apache Software Foundation (ASF) under one
{code}
updated it.
3) System.setProperty("fi.enabledOOM", null); also changed to
System.setProperty("fi.enabledOOM", "false");
because can not set null in props.
Also changed the check in aspectj file to check with true.
To be frank, i am not familiar with aspectJ programs.
So, requesting Cos to review once with my changes. One more thing is when i ran
the tests with your command, i don't see any aspects injected in to
DataXceiver.class and not running test. Not sure my compilations has the
problems with aspectj. Since this is urgent for some of the load tests running
by Konstantin, i updated the patch here.
Konstantin, can you check the patch and give the test run once.
Thanks,
Uma
