Impala JDBC - Query fails on the first run

Hi,

 

When we are querying from dashboard to Impala through a JDBC connection , the query is failing for the first run which can be seen from the Cloudera Manager Impala queries page and Impala automatically retries the query and returns data on the second run to the dashboard.

 

Due to this the dashboard is becoming slow as it is taking twice the time of the query.Could anyone throw some light for the root cause of this and a solution for it?

 

Thanks,

Renuka

Hi @renuka20,

 

What is the limit of memory that you have configure to this service?
