> In some cases, users are using the REPL LOAD command incorrectly. It does not 
> really throw any meaningful error/warning message, and as expected it does 
> not replicate the database as well.
> For example,
> {code:java}
> repl load target_db with 
> ('hive.repl.rootdir'='hdfs://c3649-node2.coelab.cloudera.com:8020/user/hive/repl',
>  'hive.repl.include.external.tables'= 'true', 
> 'hive.repl.replica.external.table.base.dir'='hdfs://c3649node2.coelab.cloudera.com:8020/warehouse/tablespace/external/hive/target_db.db'){code}
> The above command does not follow the REPL LOAD syntax. This does not produce 
> any error message, nor it replicates the database. So, it causes confusion.
