isEmptyPath() to use ContentSummary cache -----------------------------------------
Key: HIVE-2030 URL: https://issues.apache.org/jira/browse/HIVE-2030 Project: Hive Issue Type: Improvement Reporter: Siying Dong Assignee: Siying Dong Priority: Minor addInputPaths() calls isEmptyPath() for every input path. Now every call is a DFS namenode call. Making isEmptyPath() to use cached ContentSummary, we should be able to avoid some namenode calls and reduce latency in the case of multiple partitions. -- This message is automatically generated by JIRA.
