Solution:
The file system of Hadoop obtained in linkis is implemented through
hdfsutils class, so we put Kerberos in this class. Users can see the logic of
this class. The login modes supported now are as follows:
if(KERBEROS_ENABLE.getValue){
val path =newFile(KEYTAB_FILE.getValue ， userName +".keytab").getPath
val user =getKerberosUser(userName)
UserGroupInformation.setConfiguration(getConfiguration(userName))
UserGroupInformation.loginUserFromKeytabAndReturnUGI(user， path)
}else{
UserGroupInformation.createRemoteUser(userName)
}
wds.linkis.keytab.enable=true
wds.linkis.keytab.file=/appcom/keytab/ #keytabPlace a directory that stores
the of multiple usersusername.keytabDocuments
wds.linkis.keytab.host.enabled=false #Whether the client is authenticated
with the principal
wds.linkis.keytab.host=127.0.0.1#Principle authentication needs to bring the
client IP
