----------------------------------
Summary: Namenode metric
"rpc.RetryCache/NameNodeRetryCache.CacheHit" can't be correctly processed by
Ganglia
Key: HADOOP-10441
URL: https://issues.apache.org/jira/browse/HADOOP-10441
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.4.0
Reporter: Jing Zhao
Assignee: Jing Zhao
Priority: Minor
The issue is reported by [~dsen]:
Recently added Namenode metric "rpc.RetryCache/NameNodeRetryCache.CacheHit"
can't be correctly processed by Ganglia because its name contains "/"
Proposal: Namenode metric "rpc.RetryCache/NameNodeRetryCache.CacheHit" should
be renamed to "rpc.RetryCache.NameNodeRetryCache.CacheHit"
Here - org.apache.hadoop.ipc.metrics.RetryCacheMetrics#RetryCacheMetrics
{code}
RetryCacheMetrics(RetryCache retryCache) {
name = "RetryCache/"+ retryCache.getCacheName();
registry = new MetricsRegistry(name);
if (LOG.isDebugEnabled()) {
LOG.debug("Initialized "+ registry);
}
}
{code}
