> In the event of lens server restart, We can not obtain the query result by
> calling "/queryuiapi/queries/{queryHandle}/httpresultset" API as
> LensPersistentResult does not get created. This is because
> QueryOutputFormatter variable in QueryContext object is always null.This
> QueryOutputFormatter is important to create LensPersistedResultSet (see
> getResultset() method in QueryExecutionServiceImpl class) .
> Reason : One can see that QueryOutputFormatter variable in QueryContext class
> is not serialized. Therefore, on server restart, this variable is always null
> in QueryContext for all queries.
