bigdata_ambari修改hiveserver_metastore链接库(从0.14 升级到1.2.1 )

第一步:【db升级 ,先看第二步】

  cd到 hive的 metastore  upgrade目录 

 cd /usr/hdp/2.5.0.0-1245/hive/scripts/metastore/upgrade/mysql 

 source 历史版本至升级版本的sql 

技术分享

第二步:

  修改ambari hivemeta 链接的db ,重启 。 重启过程中有错 处理方案如下 【下次建议直接执行第二步,怀疑ambari会帮忙执行db升级】

drop index PCS_STATS_IDX on part_col_stats;
SET FOREIGN_KEY_CHECKS = 0;
drop table txns;
drop table txn_components;
drop table completed_txn_components;
drop table  compaction_queue;
drop table  completed_compactions;
drop table  aux_table;
drop table  next_compaction_queue_id;
drop table next_txn_id;
drop table next_lock_id;
drop table  hive_locks;
drop table write_set;
delete from VERSION;
SET FOREIGN_KEY_CHECKS = 1;
drop index  CONSTRAINTS_PARENT_TABLE_ID_INDEX on KEY_CONSTRAINTS;

----下边儿不用执行,只是操作过程中,有删除表且有值得操作 

---next_txn_id  next_lock_id   next_txn_id next_compaction_queue_id has one value 1 
VERSION; has value
VER_ID | SCHEMA_VERSION | VERSION_COMMENT               |
+--------+----------------+-------------------------------+
|      1 | 1.2.1000       | Hive release version 1.2.1000
