Grant Henke created IMPALA-9903: ----------------------------------- Summary: Queries on a Kudu table call openTable multiple times Key: IMPALA-9903 URL: https://issues.apache.org/jira/browse/IMPALA-9903 Project: IMPALA Issue Type: Improvement Components: Frontend Affects Versions: Impala 3.4.0 Reporter: Grant Henke
When testing the results of KUDU-1802 I saw that each query ran would result in 5 GetTableSchema requests to the Kudu master server. The request comes from each KuduClient.openTable call in the Impala frontend. https://github.com/apache/impala/search?l=Java&q=openTable Ideally Impala would only call KuduClient.openTable once and then use the returned KuduTable object for the length of the query. That would result in 5x fewer remote RPC calls to the Kudu master server per query. -- This message was sent by Atlassian Jira (v8.3.4#803005)
