Sahil Takiar created IMPALA-9138: ------------------------------------ Summary: Classify certain errors as retryable Key: IMPALA-9138 URL: https://issues.apache.org/jira/browse/IMPALA-9138 Project: IMPALA Issue Type: Sub-task Components: Backend Reporter: Sahil Takiar Assignee: Sahil Takiar
Impala should be able to classify certain errors as "retryable". This can be done by modifying the {{TStatus}} object to have a "type". For now, the only types can be "GENERAL" and "RETRYABLE". This way when a {{TStatus}} object is created, it can be marked as retryable. If the {{TStatus}} is retryable, the Coordinator can trigger a retry of the query. This approach allows us to incrementally mark more and more errors as retryable as necessary. For now, just RPC failures will be marked as retryable. -- This message was sent by Atlassian Jira (v8.3.4#803005)
