从Oracle JDK 8迁移到Cloudera集群中的Open JDK 8后的假冒问题

Question

最近，我从Oracle JDK 8迁移到了Cloudera的Open JDK 8（版本：openjdk-1.8.0.242.b08）。 Cloudera版本为5.16.2。我启用了Kerberos和TLS。当我使用Oracle JDK时，不会发生以下问题，但是当我切换到Open JDK时，会出现以下错误。请注意，代理用户已从CM-> HDFS->配置中启用。

Answer 1

OpenJDK 8u242中添加的功能之一是在其Kerberos客户端中支持动态跨领域引用，请参见其JDK-8223172的“规范”部分。因此，您可能想尝试在HADOOP_OPTS中添加-Dsun.security.krb5.disableReferrals=true，这实际上会禁用此新功能。

请注意，根据Cloudera docs，CDH 5.16已使用OpenJDK 8u212版进行了测试。
