【原创】大叔经验分享（41）hdfs开启kerberos之后报错Encryption type AES256 CTS mode with HMAC SHA1-96 is not supported/e

hdfs开启kerberos之后，namenode报错，连不上journalnode

journalnode也有报错：

2019-03-15 20:21:01,014 INFO org.apache.hadoop.ipc.Server: Socket Reader #1 for port 8485: readAndProcess from client 192.168.0.56 threw exception [javax.security.sasl.SaslException: GSS initiate failed [Caused by GSSException: Failure unspecified at GSS-API level (Mechanism level: Encryption type AES256 CTS mode with HMAC SHA1-96 is not supported/enabled)]]

这个是因为jce的问题，下载地址

https://www.oracle.com/technetwork/java/javase/downloads/jce8-download-2133166.html

下载之后解压得到

# ls -l UnlimitedJCEPolicyJDK8/
total 16
-rw-rw-r-- 1 root root 3035 Dec 21  2013 local_policy.jar
-rw-r--r-- 1 root root 7323 Dec 21  2013 README.txt
-rw-rw-r-- 1 root root 3023 Dec 21  2013 US_export_policy.jar

拷贝至jre对应目录

# cp UnlimitedJCEPolicyJDK8/*.jar $JAVA_HOME/jre/lib/security

然后重启hdfs即可
