[jira] [Commented] (SPARK-33458) Hive partition pruning support Contains, StartsWith and EndsWith predicate
[ https://issues.apache.org/jira/browse/SPARK-33458?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17769889#comment-17769889 ]
dzcxzl commented on SPARK-33458:
--------------------------------
After [HIVE-22900|https://issues.apache.org/jira/browse/HIVE-22900] (HMS 4.0), like filter partition supports direct sql. Now Spark uses .* method, which may cause incorrect results.
Because .* is the way to write JDO query, direct sql must use %.
