Hi all, I got a problem when using Hive 0.7.1. After I created a table with JDO failure, I can still find the table by using 'show tables;'.
I grep the code and find there is a transaction mechanism when hive interacts with metastore. However, it seems that the transaction doesn't work. I have tested this for several times. I manually throw an exception before ObjectStore commit the 'CREATE TABLE' transaction. But I can find that a new record in TBLS in mysql. So I guess meta data didn't rollback correctly. I also notice this could also happen on Hive 0.8 and 0.9. However, I haven't tested it. I think this is a fatal error and can make hive metastore unavailable. Is there anyone can help me solve this problem? Thanks. Kai Zhang
