[jira] [Created] (IMPALA-9227) Test coverage for query retries when
there is a network partition
Sahil Takiar created IMPALA-9227:
------------------------------------
Summary: Test coverage for query retries when there is a network partition
Key: IMPALA-9227
URL: https://issues.apache.org/jira/browse/IMPALA-9227
Project: IMPALA
Issue Type: Sub-task
Components: Backend
Reporter: Sahil Takiar
The initial version of transparent query retries just adds coverage for retrying a query if an impalad crashes. Now that the Impala has an RPC fault injection framework (IMPALA-8138) based on debug actions, integration tests can introduce network partitions between two impalad processes.
Node blacklisting should cause the Impala Coordinator to blacklist the nodes with the network partitions (IMPALA-9137), and then transparent query retries should cause the query to be successfully retried.
