kerberos权限认证问题

[#1]

使用的ambari管理的集群，yarn的timeline切换成外置hbase，发现没有权限写入hbase，这个时候应该怎么调整这个权限，

报错如下:

INFO client.RpcRetryingCallerImpl (RpcRetryingCallerImpl.java:callWithRetries(134)) - Call exception, tries=7, retries=7, started=8193 ms ago, cancelled=false, msg=Call to ambari/hostname:16020 failed on local exception: java.io.IOException: org.apache.hbase.thirdparty.io.netty.handler.codec.DecoderException: org.apache.hadoop.ipc.RemoteException(javax.security.sasl.SaslException): GSS initiate failed, details=row 'prod.timelineservice.application,yarn_cluster!ambari-qa!DistributedShell��|��-���|��G���,99999999999999' on table 'hbase:meta' at region=hbase:meta,,1.1588230740, hostname=hostname,16020,1662630353507, seqNum=-1

Transation:

In the cluster managed by ambari, the timeline of yarn is switched to external hbase, and it is found that there is no permission to write to hbase. How to adjust this permission at this time?

The error is as follows: I
