Hi,
I am trying to login to secure cluster with keytabs using below methods. It
works fine if the token is not expired. My process runs for long time ( web
app from tomcat). Keep getting below exceptions after the token expire time and
connection fails if the user tries to view data from web page.
What is the better way of handling connections? How to refresh keys
automatically?. Is there a spring implementation for managing connections? If
yes, can you share sample code.
UserGroupInformation.setConfiguration(conf);
UserGroupInformation.loginUserFromKeytab("hbase.myclient.principal",
"hbase.myclient.keytab");
