solrconfig.xml配置如下:
<bool name="solr.hdfs.security.kerberos.enabled">true</bool>
<str name="solr.hdfs.security.kerberos.keytabfile">/etc/security/keytabs/icps.app.keytab</str>
<str name="solr.hdfs.security.kerberos.principal">icps/[email protected]</str>
我的HDFS是通过kerberos认证的, 我就配置了kerberos认证方式
但是却报我HDFS配置变量hadoop.security.authentication是simple而不是kerberos
我自己写一个测试程序new 一个configuration把这个变量值打印出来,确实是kerberos,但是我的配置文件里面并没有显示配置这个值,这个默认值就是kerberos
于是我怀疑是HDFS的配置文件加载错了,我就显示指定HDFS配置文件的加载路径:
java -Dsolr.hdfs.confdir=/apps/icps/site -jar start.jar
结果就没报错了
