Lampros Smyrnaios 66cd28f70a - Fix not using the "export HADOOP_USER_NAME" statement in "createPDFsAggregated.sh", which caused permission-issues when creating tables with Impala. 
- Remove unused "--user" parameter in "impala-shell" calls.
- Code polishing.

Lampros Smyrnaios 3095047e5e Miscellaneous updates to the copying operation to Impala Cluster: 
- Fix not breaking out of the VIEWS-infinite-loop when the "SHOULD_EXIT_WHOLE_SCRIPT_UPON_ERROR" is set to "false".
- Exit the script when no HDFS-active-node was found, independently of the "SHOULD_EXIT_WHOLE_SCRIPT_UPON_ERROR".
- Fix view_name-recognition in a log-message, by using the more advanced "Perl-Compatible Regular Expressions" in "grep".
- Add error-handling for "compute stats" errors.

Lampros Smyrnaios e3f28338c1 Miscellaneous updates to the copying operation to Impala Cluster: 
- Assign the WRITE and EXECUTE permissions to the DBs' HDFS-directories, in order to be able to create tables on top of them, in the Impala Cluster.
- Make sure the "copydb" function returns early, when it encounters a fatal error, while respecting the "SHOULD_EXIT_WHOLE_SCRIPT_UPON_ERROR" config.

- Add a configuration-"switch" to control whether the script exits upon an error or not.
- Allow the script to exit when a table could not be created.
- Show the elapsed time for processing each database.

Lampros Smyrnaios 49af2e5740 Miscellaneous updates to the copying operation to Impala Cluster: 
- Update the algorithm for creating views that depend on other views; overcome some bash-instabilities.
- Upon any error, fail the whole process, not just the current DB-creation, as those errors usually indicate a bug in the initial DB-creation, that should be fixed immediately.
- Enhance parallel-copy of large files by "hadoop distcp" command.
- Reduce the "invalidate metadata" commands to just the current DB's tables, in order to eliminate the general overhead on Impala.
- Show the number of tables and views in the logs.
- Fix some log-messages.

Lampros Smyrnaios d46b78b659 dhp-stats-update: 
- Set Steps 2-7 and 9 to limit the amount of files generated by Spark, from 8000, down to 100, to improve file-transfer and querying performance.
- Allow the workflow to run up to Step10. The Step11 seems to have some issues even when using hive-action.

Lampros Smyrnaios 6f2ebb2a52 Revert Step8 and Step11 to use Hive again, since their "UPDATE" statements are not supported by Spark. 2024-04-18 15:35:03 +03:00

Lampros Smyrnaios db33f7727c Update "dhp-stats-update" workflow to use "spark"-actions, instead of "hive" ones. 
Note: Currently the code is set to only test the "Step1".

- Update the algorithm for creating views that depend on other views.
- Add check for successful execution of the "hadoop distcp" command.

- Code polishing.
 2024-04-12 15:36:13 +03:00
Lampros Smyrnaios abf0b69f29 Upgrade the copying operation to Impala Cluster: 
- Use only hive commands in the Ocean Cluster, as the "impala-shell" will be removed from there to free-up resources.
- Hugely improve the performance in every aspect of the copying process: a) speedup file-transferring and DB-deletion, b) eliminate permissions-assignment, "load" operations and "use $db" queries, c) retry only the "create view" statements and only as long as they depend on other non-created views, instead of trying to recreate all tables and views 5 consecutive times.
- Add error-checks for the creation of tables and views.
 2024-04-11 17:12:12 +03:00
Lampros Smyrnaios b7c8acc563 - Update the code which acquires the "IMPALA_HDFS_NODE", to test the "tmp"-dir, instead of the base-dir and introduce retries, to overcome potential file-system failures. This change was suggested by "Sebastian Tymkow" and "Grzegorz Bakalarski". 
- Fix typos.
