大叔经验分享（133）hive元数据中location修复

假如hive中table或者partition的location错误或者丢失，需要批量修复，可以参考如下步骤：

修复table的location

hdfs dfs -ls /data/hive/warehouse/$db | awk '{print $8}' |sed '1d' | awk -F '/' '{print "alter table "$5"."$7" set location ""$0"";"}'

输出的sql在hive中执行

修复partition的location

update DBS d, TBLS t, SDS ts, PARTITIONS p, SDS ps set ps.location = concat(ts.location, '/', p.part_name)
-> where d.db_id = t.db_id and t.sd_id = ts.sd_id and p.tbl_id = t.tbl_id and p.sd_id = ps.sd_id
-> and d.name = '$db';>

在hive元数据库中执行以上命令

确认修复

select * from $db.$table limit 10
