Generating a sequential order in a distributed processing query is not possible with simple UDFs. This is because the approach will require some centralised entity to keep track of the counter, which will also result in severe inefficiency for distributed queries and is not recommended to apply.

@Revlin Abbi - That error is because of wrong version of mysql connector jar file. ls -l /usr/share/java/mysql* if you want to over come the problem. please use --driver com.mysql.jdbc.Driver it will solve the issues, but recommendation is to use the right version of mysql connector jar.

@Deepesh i required to get the user . if i call the variable ${user.name} - i will get the value as hive, but i required to get the user . The reason we'd like this is to store AWS access credentials for S3 on each user's HDFS directory (e.g., hdfs://user/jkotireddy/aws_credentials) and have the S3 libraries automatically pick them up. We'd like to set this variable to something like "hdfs://user/${user.name}/aws_credentials". - want a config variable which gives me the Hadoop-level effective user.

In the Hadoop config files, we have some limited variable substitution, e.g. ${user.name} is replaced by the Linux-level effective user of the hadoop daemon that accesses a given config. Is there a substitution variable to get the Hadoop-level effective user? For instance, if I connect as “jkotireddy” to HiveServer2 using Beeline, ${user.name} expands to "hive" because that's the Linux-level effective user of HiveServer2; are there any other configuration variables which gives “jkotireddy” ?
