-------------------------------------------
Summary: HAWQ hdfs-client / output.replace-datanode-on-failure
should be set to true by default
Key: AMBARI-15449
URL: https://issues.apache.org/jira/browse/AMBARI-15449
Project: Ambari
Issue Type: Bug
Reporter: Alexander Denissov
Assignee: Alexander Denissov
Priority: Minor
On large cluster, replace-datanode-on-failure should be set to true, but on
small clusters (developers environment or testing environment), it should be
set to false, otherwise, if datanodes are overloaded, it will report error.
This is the reason it was set to false by default earlier.
Ambari should set it to true when cluster size > 4, otherwise set it to false.
