Hive安装过程中出现 The reference to entity "createDatabaseIfNotExist" must end with the ';' delimiter.问题,具体如下所示:
[Fatal Error] hive-site.xml:132:95: The reference to entity "createDatabaseIfNotExist" must end with the ';' delimiter.
14/10/23 11:15:04 FATAL conf.Configuration: error parsing conf file:/usr/local/apache-hive-0.13.1-bin/conf/hive-site.xml
org.xml.sax.SAXParseException; systemId: file:/usr/local/apache-hive-0.13.1-bin/conf/hive-site.xml; lineNumber: 132; columnNumber: 95; The reference to entity "createDatabaseIfNotExist" must end with the ';' delimiter.
因为hive-site.xml中的javax.jdo.option.ConnectionURL配置项引起的,如下所示:
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hive_hdp?characterEncoding=UTF-8&createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</description>
</property>
正确配置如下:
<property>
<name>javax.jdo.option.ConnectionURL</name>
<value>jdbc:mysql://localhost:3306/hive_hdp?characterEncoding=UTF-8&createDatabaseIfNotExist=true</value>
<description>JDBC connect string for a JDBC metastore</description>
</property>
这是因为xml文件中的编码规则引起的。
在xml文件中有以下几类字符要进行转义替换如下表所示:
所以javax.jdo.option.ConnectionURL项中的&符号需要用&表示。
