Sahil Takiar created IMPALA-8962: ------------------------------------ Summary: FETCH_ROWS_TIMEOUT_MS should apply before rows are available Key: IMPALA-8962 URL: https://issues.apache.org/jira/browse/IMPALA-8962 Project: IMPALA Issue Type: Bug Components: Clients Reporter: Sahil Takiar Assignee: Sahil Takiar
IMPALA-7312 added a fetch timeout controlled by the query option {{FETCH_ROWS_TIMEOUT_MS}}. The issue is that the timeout only applies after the *first* batch of rows are available. The issue is that both Beeswax and HS2 clients call {{request_state->BlockOnWait}} inside {{ImpalaServer::FetchInternal}}. The call to {{BlockOnWait}} blocks until rows are ready to be consumed via {{ClientRequestState::FetchRows}}. So clients can still end up blocking indefinitely waiting for the first row batch to appear. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-all-unsubscr...@impala.apache.org For additional commands, e-mail: issues-all-h...@impala.apache.org
