Subhasis Gorai created HIVE-26931: ------------------------------------- Summary: REPL LOAD command does not throw any error for incorrect syntax Key: HIVE-26931 URL: https://issues.apache.org/jira/browse/HIVE-26931 Project: Hive Issue Type: Bug Components: HiveServer2 Reporter: Subhasis Gorai
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'); INFO : Compiling command(queryId=hive_20221201113704_08ee46a6-ede9-4c92-9502-82b9fbc416bd): 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') INFO : Semantic Analysis Completed (retrial = false) INFO : Created Hive schema: Schema(fieldSchemas:null, properties:null) INFO : Completed compiling command(queryId=hive_20221201113704_08ee46a6-ede9-4c92-9502-82b9fbc416bd); Time taken: 0.051 seconds INFO : Executing command(queryId=hive_20221201113704_08ee46a6-ede9-4c92-9502-82b9fbc416bd): 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') INFO : Completed executing command(queryId=hive_20221201113704_08ee46a6-ede9-4c92-9502-82b9fbc416bd); Time taken: 0.001 seconds INFO : OK No rows affected (0.065 seconds) 0: jdbc:hive2://nightly7x-us-bj-3.nightly7x-u>{code} Ideally, since this is a wrong command, it should throw an error. -- This message was sent by Atlassian Jira (v8.20.10#820010)
