在spark中使用hivecontext时也会遇到这个异常，原因在于hive的metastore表VERSION中存在重复的记录，从而报出存在多条hive版本的异常信息
VER_ID SCHEMA_VERSION VERSION_COMMENT
ID主键 Hive版本 版本说明
1 0.13.0 Set by MetaStore
解决办法：
- 删除VERSION表中多余的版本信息即可解决
2.修改hive-site.xml中配置，取消metastore版本信息校验
hive.metastore.schema.verification false 这个异常信息多次出现，每次都是由spark的一台work插入进去，正好这台机器是虚拟机节点非物理机，猜测是在这台虚拟机网络环境不好的时候，检查不到hive metastore中version版本信息再插入一条新的记录导致重复异常的
