### Why are the changes needed?
<!--
Currently we have the logic to deal with the JDBC keytab provided by the
"--files" option
if (keytabParam != null && FilenameUtils.getPath(keytabParam).isEmpty)
{
val result = SparkFiles.get(keytabParam)
logDebug(s"Keytab path not found, assuming --files, file name used on
executor: $result")
result
}
else {
Spark has already created the soft link for any file submitted by the
"--files" option. So there is no need to call the SparkFiles.get to absolute
path of the keytab file. We can directly use the variable keytabParam as the
keytab file path.
`
Moreover, SparkFiles.get will get a wrong path of keytab. In a running Spark
cluster, the keytab is distributed to the following location
/var/opt/hadoop/temp/nm-local-dir/usercache/testusera1/appcache/application_1628584679772_0003/filecache/12/testusera1.keytab
but SparkFiles.get brings the following wrong location
/var/opt/hadoop/temp/nm-local-dir/usercache/testusera1/appcache/application_1628584679772_0003/spark-8fb0f437-c842-4a9f-9612-39de40082e40/userFiles-5075388b-0928-4bc3-a498-7f6c84b27808/testusera1.keytab
