Zikun updated SPARK-36493:
--------------------------
Description:
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
}
Spark has already created the soft link for any file submitted by the "--files"
option. Here is an example.
testusera1.keytab ->
/var/opt/hadoop/temp/nm-local-dir/usercache/testusera1/appcache/application_1628584679772_0003/filecache/12/testusera1.keytab
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 different path of keytab
