Hive 问题汇总

1 Cannot execute statement: impossible to write to binary log since BINLOG_FORMAT = STATEMENT…

当启动Hive的时候报错：

Causedby: javax.jdo.JDOException: Couldnt obtain a new sequence (unique id) : Cannot execute statement: impossible towriteto binary logsince BINLOG_FORMAT = STATEMENT andat least one table uses a storage engine limited to row-based logging. InnoDB is limited to row-logging when transaction isolation level is READ COMMITTED or READ UNCOMMITTED.

NestedThrowables:

java.sql.SQLException: Cannot execute statement: impossibletowriteto binary logsince BINLOG_FORMAT = STATEMENT andat least one table uses a storage engine limited to row-based logging. InnoDB is limited to row-logging when transaction isolation level is READ COMMITTED or READ UNCOMMITTED.

这个问题是由于hive的元数据存储MySQL配置不当引起的，可以这样解决：

mysql>setglobal binlog_format='MIXED';

2 For direct MetaStore DB connections, we don’t support retries at the client level.

当在Hive中创建表的时候报错：

FAILED: ExecutionError,return code 1from org.apache.hadoop.hive.ql.exec.DDLTask. MetaException(message:For direct MetaStore DB connections, we don't support retries at the client level.)

这是由于字符集的问题，需要配置MySQL的字符集：

mysql> alter database hivecharacterset latin1;

3 HiveConf of name hive.metastore.local does not exist

当执行Hive客户端时候出现如下错误：

WARN conf.HiveConf: HiveConfofname hive.metastore.localdoesnot exist

这是由于在0.10 0.11或者之后的HIVE版本 hive.metastore.local 属性不再使用。将该参数从hive-site.xml删除即可。

4 Permission denied: user=anonymous, access=EXECUTE, inode=”/tmp”

在启动Hive报如下错误：

(Permissiondenied: user=anonymous, access=EXECUTE, inode="/tmp":hadoop:supergroup:drwx------

这是由于Hive没有hdfs:/tmp目录的权限，赋权限即可：

hadoop dfs-chmod-R777 /tmp

5 hive drop table table_name 卡死（长时间没有反应）

在hive中,show tables,create 等命令能正常执行,删除表drop table x时,会出现卡住的现象.

进入mysql,

show variables like 'char%'

可以看到

按理说是正确的.

后面发现,是在建好hive数据库后,没有第一时间将character_set_database编码由utf8修改为latin1.而是去hive中create了一张表.而后才将character_set_database编码由utf8改成了latin

解决办法:

在mysql中将drop hive

重新create hive,

修改编码,alter database hive character set latin1

进入hive shell

创建表,drop表,正常!
