Subject [jira] [Created] (DRILL-5872) Deserialization of profile JSON fails due to totalCost being reported as "NaN"
Date Thu, 12 Oct 2017 20:19:00 GMT
Kunal Khatua created DRILL-5872:
-----------------------------------

             Summary: Deserialization of profile JSON fails due to totalCost being reported
as "NaN"
                 Key: DRILL-5872
                 URL: https://issues.apache.org/jira/browse/DRILL-5872
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.12.0
            Reporter: Kunal Khatua
            Assignee: Paul Rogers
            Priority: Blocker
             Fix For: 1.12.0


With DRILL-5716 , there is a change in the protobuf that introduces a new attribute in the
JSON document that Drill uses to interpret and render the profile's details. 
The totalCost attribute, used as a part of showing the query cost (to understand how it was
assign to small/large queue), sometimes returns a non-numeric text value {{"NaN"}}. 

This breaks the UI with the messages:
{code}
Failed to get profiles:
unable to deserialize value at key 2620698f-295e-f8d3-3ab7-01792b0f2669
{code}
