[jira] [Commented] (FLINK-15049) Compile error when hash join with timestamp type key

    [ https://issues.apache.org/jira/browse/FLINK-15049?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16987625#comment-16987625 ] 

Zhenghua Gao commented on FLINK-15049:
--------------------------------------

LongHashJoinGenerator should convert SqlTimestamp to Long by genGetLongKey when precision of TimestampType is less than  or equals to 3.

> Now, internal format of timestamp type has been modified to SqlTimestamp, but in LongHashJoinGenerator, still convert it to long directly in genGetLongKey.
> This should be a bug when hash join with timestamp type key.
