Xuefu Zhang commented on HIVE-3611:
-----------------------------------
[~leftylev]
1. Yes, binary type is in the list of JdbcColumn, but data can only be
retrieved via getString() assuming data is encoded as base64. This JIRA adds
getBinaryStream(), and binary data is retried as binary.
2. In my opinion, old JDBC (org.apache.hadoop.hive package) is in
maintenance/deprecated mode, and we should not be adding new features (data
types). However, this is not followed strictly by everyone. Thus, disparities
may be seen.
