For what i know, every sqltask will execute this function ( create
connection from keytab not from cache ) , so only make sure sqltask not run too
long ( over 1 day ) and i see this is possible.
`
// if upload resource is HDFS and kerberos startup
CommonUtils.loadKerberosConf();
// create connection
connection = createConnection();
`
