Subject Re: Problem starting Hive with local metastore on mysql
Date Thu, 20 Jan 2011 00:38:12 GMT
Thanks!

Now I am hitting mysql bug of max key length: Specified key was too long;
max key length is 767 bytes

11/01/19 16:34:47 ERROR DataNucleus.Datastore: Error thrown executing CREATE
TABLE `SD_PARAMS`
(
    `SD_ID` BIGINT NOT NULL,
    `PARAM_KEY` VARCHAR(256) BINARY NOT NULL,
    `PARAM_VALUE` VARCHAR(767) BINARY NULL,
    PRIMARY KEY (`SD_ID`,`PARAM_KEY`)
) ENGINE=INNODB : Specified key was too long; max key length is 767 bytes
