[jira] [Commented] (HIVE-16927) LLAP: Slider takes down all daemons
when some daemons fail repeatedly
[ https://issues.apache.org/jira/browse/HIVE-16927?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16056766#comment-16056766 ]
Prasanth Jayachandran commented on HIVE-16927:
----------------------------------------------
One way to fix this is to set higher threshold for failures. Higher threshold can easily be reached on bigger clusters. If the threshold is set to 20, then 2 failures on 10 nodes will bring down all daemons. Ideally, we want slider to retry failures on a different node.
