This version of ORC is newer > (1.7.3) than what Hive uses (1.6.9). > Later on we could face compatibility issues when trying to reconstruct an > OrcTail object with a 1.6.9 reader from the bytes that the 1.7.3 reader > serialized. We need to invert the direction as we can rely more on backward > compatibility than on forward compatibility of ORC. -- This message was sent by Atlassian Jira (v8.20.7#820007)
