Hi Guys:
I wonder about, it is work that flink on yarn deploy on no
authentication Hadoop cluster, access hbase deploy on Kerberos
authentication Hadoop cluster? If work, what I need to do. I already config
flink-conf-yaml properties "security.kerberos.login.keytab" and
"security.kerberos.login.principal".
And i found the next paragraph in flink official website :
https://ci.apache.org/projects/flink/flink-docs-release-1.9/ops/security-ker
beros.html
Hadoop Security Module
This module uses the Hadoop UserGroupInformation (UGI) class to establish a
process-wide login user context. The login user is then used for all
interactions with Hadoop, including HDFS, HBase, and YARN.
If Hadoop security is enabled (in core-site.xml), the login user will have
whatever Kerberos credential is configured. Otherwise, the login user
conveys only the user identity of the OS account that launched the cluster.
Thanks a lot !
