 Summary: Document Fix for dfs.ha.zkfc.port
 Key: HDFS-16823
 URL: https://issues.apache.org/jira/browse/HDFS-16823
 Project: Hadoop HDFS
  Issue Type: Bug
  Components: configuration
Affects Versions: 3.3.4
Reporter: teng wang


There is a control dependency between dfs.ha.automatic-failover.enabled and 
dfs.ha.zkfc.port. That is, dfs.ha.zkfc.port can only work if 
dfs.ha.automatic-failover.enabled is set to true. However, the document does 
not mention it.

It is suggested to fix the document(hdfs-default.xml) of dfs.ha.zkfc.port.

[jira] [Created] (HDFS-16820) Document Fix for hadoop.user.group.metrics.percentiles.intervals

[teng wang (Jira)]

teng wang created HDFS-16820:


 Summary: Document Fix for 
hadoop.user.group.metrics.percentiles.intervals
 Key: HDFS-16820
 URL: https://issues.apache.org/jira/browse/HDFS-16820
 Project: Hadoop HDFS
  Issue Type: Bug
  Components: configuration
Affects Versions: 3.3.4
Reporter: teng wang


The default value of hadoop.user.group.metrics.percentiles.intervals is 
dfs.metrics.percentiles.intervals. If 
hadoop.user.group.metrics.percentiles.intervals is not set, it would take the 
value of dfs.metrics.percentiles.intervals. 

It is suggested to fix the document of hdfs-default.xml

 
{code:java}
// 

  hadoop.user.group.metrics.percentiles.intervals
  
  
    A comma-separated list of the granularity in seconds for the metrics
    which describe the 50/75/90/95/99th percentile latency for group resolution
    in milliseconds.
    By default, percentile latency metrics are disabled.
+    If not specified, the value of dfs.metrics.percentiles.intervals is used 
as the default value.
  
 {code}
