Hive字符集問題

創建表失敗

• hive創建表失敗，報錯
  FAILED: Execution Error,
  return code 1 from org.apache.hadoop.hive.ql.exec.DDLTask.
  MetaException(message:For direct MetaStore DB
  connections, we don’t support retries at the client
  level.)

錯誤信息很不明確，解決思路：

• 找日誌
  日誌目錄：$HIVE_HOME/conf/hive-log4j.properties.template
  日誌目錄配置是由

          1. hive.log.dir=${java.io.tmpdir}/${user.name}
  

  配置

• 查看日誌
  ERROR [main]: Datastore.Schema (Log4JLogger.java:error(115)) - An exception was thrown while adding/validating class(es) :
  Specified key was too long; max key length is 767 bytes
  com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Specified key was too long; max key length is 767 bytes
  這個錯誤是字符集問題

*解決方法
更改hive元數據庫字符類型
alter database basic01 character set latin1;
use basic01;
alter table PARTITIONS convert to character set latin1;
alter table PARTITION_KEYS convert to character set latin1;
