[jira] [Commented] (HIVE-22406) TRUNCATE TABLE fails due MySQL
limitations on limit value
[ https://issues.apache.org/jira/browse/HIVE-22406?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16960303#comment-16960303 ]
Naveen Gangam commented on HIVE-22406:
--------------------------------------
In case of truncate table, the code specified Integer.MAX_VALUE for the limit, but its real intention is to get all the partitions for the table. In this case, using {{-1}} instead of MAX_VALUE is to be used as it returns all the partitions. Prior behavior was to convert this value to short, which would have secretly used {{-1 //nolimit}} under the covers as well. But I think this is more appropriate semantically.

> HMS currently has some APIs that accepts an integer limit value. Prior to the change in HIVE-21734, HMS was silently converting this int to short and thus we havent seen this issue. But semantically, its incorrect to do so quietly.

> We cannot change the RawStore api to accept shorts instead of ints.
> So we have to fix the caller to use a lower limit instead of Integer.MAX_VALUE.
