读取hbase是我使用的catalog是hive，不用再写建表语句然后再查），当我用sql-client尝试的时候报错。 读取正常的hive是可以正常读取的，但是读取hive on hbase表却报 [ERROR] Could not execute SQL statement. Reason: org.apache.flink.table.catalog.exceptions.CatalogException: Failed to get table schema from deserializer。 不知道有没有什么办法可以解决这个问题，使用spark引擎是可以读取到数据的。 18579099...@163.com
