[jira] [Updated] (TEZ-4139) Tez should consider node information
for computing failure fraction
[ https://issues.apache.org/jira/browse/TEZ-4139?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
László Bodor updated TEZ-4139:
------------------------------
Description:
When lots of downstream attempts fail to pull the information from source task, source task is marked as failed and it is retried. Currently failure fraction is handled by looking at unique task attempts from downstream. However, it should consider taking into account node information for computing "failureFraction".
