Summary: Compactor: Initiator should lazy evaluate findUserToRunAs() Key: HIVE-24806 URL: https://issues.apache.org/jira/browse/HIVE-24806 Project: Hive Issue Type: Improvement Reporter: Rajesh Balamohan https://github.com/apache/hive/blob/64bb52316f19426ebea0087ee15e282cbde1d852/ql/src/java/org/apache/hadoop/hive/ql/txn/compactor/Initiator.java#L232 {noformat} cache.putIfAbsent(fullTableName, findUserToRunAs(sd.getLocation(), t)); {noformat} This ends up evaluating findUserToRunAs() everytime, and looks up from FileSystem on every call (thousands of times in large database). This can be lazy initialized instead (e.g computeIfAbsent); -- This message was sent by Atlassian Jira (v8.3.4#803005)
