spark查询UNIQUE模型频繁出现异常errCode = 2, detailMessage = Only support prepare SelectStmt point query now
UNIQUE模型 已添加配置 "enable_unique_key_merge_on_write" = "true",
"light_schema_change" = "true",
"store_row_column" = "true"
且使用了 PreparedStatement 如 url = jdbc:mysql://127.0.0.1:9030/ycsb?useServerPrepStmts=true
