-----------------------------------
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.
