Tsz Wo (Nicholas), SZE commented on HDFS-4261:
----------------------------------------------
You are right. It cannot be changed to non-static. How about moving
notChangedIterations to NameNodeConnector? If we do it, we may as well move
the related code.
{code}
//NameNodeConnector
static final int MAX_NOT_CHANGED_INTERATIONS = 5;
private int notChangedIterations = 0;
boolean shouldContinue(long dispatchBlockMoveBytes) {
if (dispatchBlockMoveBytes > 0) {
notChangedIterations = 0;
} else {
notChangedIterations++;
if (notChangedIterations >= MAX_NOT_CHANGED_INTERATIONS) {
System.out.println("No block has been moved for "
+ notChangedIterations + " iterations. Exiting...");
return false;
}
}
return true;
}
{code}

> When I manually ran TestBalancerWithNodeGroup, it always timed out in my
> machine. Looking at the Jerkins report [build
> #3573|https://builds.apache.org/job/PreCommit-HDFS-Build/3573//testReport/org.apache.hadoop.hdfs.server.balancer/],
> TestBalancerWithNodeGroup somehow was skipped so that the problem was not
> detected.
