Ferdinand Xu commented on HIVE-11912: ------------------------------------- Thank you for the clarification. The original purpose for HIVE-7858 is that ORC supports this way to configure the table compression properties. The patch LGTM. One minor question about the patch: {noformat} 108 Map<String, String> defaultSerdeProps = descriptor.getDefaultSerdeProps(); 109 if (defaultSerdeProps != null) { 110 serdeProps.putAll(defaultSerdeProps); 111 } {noformat} Is that possible the original serde properties overrided by the default value? > Make snappy compression default for parquet tables > -------------------------------------------------- > > Key: HIVE-11912 > URL: https://issues.apache.org/jira/browse/HIVE-11912 > Project: Hive > Issue Type: Improvement > Components: File Formats > Reporter: Szehon Ho > Assignee: Szehon Ho > Attachments: HIVE-11912.patch > > > Snappy is a popular compression codec for Parquet, and is the default in many > Parquet applications, increasing the performance. > This change would make it the default for new Hive Parquet tables. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
