Hive使用過程當中踩過的坑

hive啓動時錯誤1

Cannot execute statement:impossible to write to binary long since BINLOG_FORMAT = STATEMENT...
當啓動時報錯
Caused by: javax.jdo.JDOException:Couldnt obtain a new sequence(unique id):Cannot execute statement:impossible to write to binary log since BINLOG_FORMAT = STATEMENT and at least one table uses a storage engine limited to row-logging when transaction isolation level is READ COMMITTED or READ UNCOMMITED.
NestedThrowables: java.sql.SQLException:Cannot execute statement:impossible to write to binary log since BINLOG_FORMAT = STATEMENT and at least one table uses a storage engine limited to row-based logging. InnoDB is limited to row-logging when transaction isolation level is READ COMMITED or READ UNCOMMITED.複製代碼

緣由：這是因爲hive的元數據存儲MYSQL配置不當引發的

解決方案1（臨時解決）：mysql> set global binlog_format='MIXED'

解決方案2（永久解決）：
修改/etc/my.cnf,添加屬性
# binary logging format - mixed recommended 
binlog_format=mixed複製代碼

hive啓動時錯誤2

Exception in thread "main" java.lang.IncompatibleClassChangeError: Found class jline.Terminal, but interface was expected

緣由：
hadoop目錄下存在老版本jline：
/hadoop-2.7.2/share/hadoop/yarn/lib：
-rw-r--r-- 1 root root   87325 Mar 10 18:10 jline-0.9.94.jar

解決：
將hive安裝路徑下的lib目錄下的jline-版本號.jar文件拷貝到hadoop安裝目錄/share/hadoop/yarn/lib下便可
如：cp -r /hive/lib/jline-2.12.jar /hadoop-2.7.2/share/hadoop/yarn/lib複製代碼

hive建表時出現

Error: Error while processing statement: 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.) (state=08S01,code=1)。複製代碼

緣由：在建立mysql時使用的字符集不對，須要修改hive數據庫的字符集。
解決：在mysql中使用命令修改hive數據庫字符集：alter database hive character set latin1;複製代碼

在drop表時卡死

緣由：因爲是先建立的表，以後再修改的hive數據庫的字符集，因此卡死。
解決：
1. 進入mysql,將mysql下創建的元數據庫hive刪除，再使用mysql從新建立，建立後修改字符集爲latin1，在mysql刪除hive數據庫時，須要將hive中止，否則mysql也會卡死。
2. 也能夠修改/etc/my.cnf文件，將裏邊涉及到字符的屬性都設置爲latin1複製代碼
