Aihua Xu created HIVE-11258: ------------------------------- Summary: The function drop_database_core() of HiveMetaStore.java may not drop all the tables Key: HIVE-11258 URL: https://issues.apache.org/jira/browse/HIVE-11258 Project: Hive Issue Type: Bug Components: Database/Schema Affects Versions: 2.0.0 Reporter: Aihua Xu Assignee: Aihua Xu
The following code in that function doesn't work properly. {noformat} int startIndex = 0; int endIndex = -1; // retrieve the tables from the metastore in batches to alleviate memory constraints while (endIndex < allTables.size() - 1) { startIndex = endIndex + 1; endIndex = endIndex + tableBatchSize; if (endIndex >= allTables.size()) { endIndex = allTables.size() - 1; } {noformat} e.g.: if we have 5 tables and tableBatchSize is 10, startIndex will be 0 and endIndex will be 4. We only drop 4 tables since sublist(startIndex, endIndex) is inclusive on startIndex and exclusive on endIndex. If total tables is larger tableBatchSize, we also have similar issues. This is discovered when I work on HIVE-11255. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
