[jira] [Comment Edited] (IMPALA-7232) Display whether fragment
instances' profile is complete
[ https://issues.apache.org/jira/browse/IMPALA-7232?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16530813#comment-16530813 ]

------------------------------------------------------------
Yes, fixing IMPALA-6741 will definitely help. A missing profile update for a particular instance just results really old timestamp in the profile. We also need a marker in the profile to indicate whether the profile is final in order to tackle situation like IMPALA-5555.

> Issue Type: Task
> Components: Distributed Exec
> Affects Versions: Impala 3.1.0
> Reporter: Michael Ho
> Assignee: Michael Ho
> Priority: Major

> While working on IMPALA-7213, it's noticed that we can fail to serialize or deserialize a profile for random reasons. This shouldn't be fatal: the fragment instance status can still be presented to the coordinator to avoid hitting IMPALA-2990. A missing profile in ReportExecStatus() RPC may result in incomplete or stale profile being presented to Impala client. It would be helpful to mark whether the profile may be incomplete and/or final in the profile output.
