> Key: HIVE-26931
> URL: https://issues.apache.org/jira/browse/HIVE-26931
> Project: Hive
> Issue Type: Bug
> Components: HiveServer2
> Reporter: Subhasis Gorai

> Priority: Major

> 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.
> {code:java}
> 0: jdbc:hive2://nightly7x-us-bj-3.nightly7x-u> repl load test_1_replica with ('hive.repl.rootdir'='hdfs://c3649-node2.coelab.cloudera.com:8020/user/repl', 'hive.repl.include.external.tables'= 'true', 'hive.repl.replica.external.table.base.dir'='hdfs://c3649node2.coelab.cloudera.com:8020/warehouse/tablespace/external/hive/test_1_replica.db');

> Ideally, since this is a wrong command, it should throw an error.
