Summary: HDFS Recommendation: dfs.datanode.du.reserved should be
set to 10%-15% of volume size
Key: AMBARI-14524
URL: https://issues.apache.org/jira/browse/AMBARI-14524
Project: Ambari
Issue Type: Bug
Components: stacks
Affects Versions: 2.1.0
Reporter: Dmytro Sen
Assignee: Dmytro Sen
Priority: Critical
Fix For: 2.4.0
d we get into a bad state with not enough nodemanagers being up. At this point
the admin tries to run the balancer and hope that it will balance very quickly.
There should be a recommendation on this value based on the disk space
available in the datanode volume. In addition, if the user sets it too low
there should be a warning saying this will cause problems if enough buffer is
not kept.
