- Add a check for when the retrieved full-texts-batch is missing some requested files and show a warn-log.
- Update dependencies.
 2023-01-23 20:23:21 +02:00
Lampros Smyrnaios d8773e6ebb - Make sure the test-environment uses a dedicated hdfs-parquet-directory.

 2023-01-10 13:34:54 +02:00

 2023-01-09 15:44:53 +02:00
Lampros Smyrnaios 9904ea5743 - Improve the stability of "UriBuilder.getPublicIP()", by using a "HttpURLConnection" to increase the connection and read timeouts and avoid timeout-exceptions. 
- Update Spring.
 2023-01-03 18:39:50 +02:00
Lampros Smyrnaios 4528d1f9be - Fix the "baseFilesLocation" being null (there was no serious problem, but multiple directories were spawned in the project's directory).

- Catch the more general "Exception", inside "FileUtils.mergeParquetFiles()", in order to be certain that the "SQLException" can also be caught.
- Code polishing.
 2022-12-09 12:46:06 +02:00
Lampros Smyrnaios 0209d24068 - Change the parquet compression from "Snappy" to "Gzip", as there is an unhandleable exception when the app is running inside a Docker Container and uses the "Snappy" compression. 
- Code polishing.
 2022-12-08 16:28:41 +02:00

- Fix error-handling in "installAndRun.sh".
- Update dependencies.
 2022-11-30 16:28:39 +02:00
Lampros Smyrnaios 6226e2298d - Upgrade the results-loading process: Instead of making thousands of sql-insert requests to Impala now we write the results to parquet files, upload them to HDFS and then import the data into the Impala tables with just 2 requests. This results in a huge performance improvement. 
One side effect of using the parquet-files, is that the timestamps are now BIGDECIMAL numbers, instead of "Timestamp" objects, but, converting them to such objects is pretty easy, if we ever need to do it.
- Code polishing.
 2022-11-10 17:18:21 +02:00

- Add comments.
 2022-09-15 23:12:05 +03:00
Lampros Smyrnaios 3e8f9c6074 Update the "UriBuilder.java" to be able to acquire the running port of the server, in case the port-number was initially set to "random" (0). Also make sure we get the "localHostAddress" and not the "localHostName", in case the public IP is not retrievable. 2022-09-12 17:04:05 +03:00

Lampros Smyrnaios 9096137008 Update documentation. 2022-04-14 14:42:36 +03:00
Lampros Smyrnaios 9b95eebb6c - Remove the obsolete "parenthesis" and "increasing duplicate-num" from the full-texts' names, before sending them to the S3-Object-Store. They now end with the "file-hash", so it is guaranteed that they will be unique. The Worker continues to produce the previous kind of names, without any disturbance. 
- Improve logging.

 2022-04-11 21:15:22 +03:00

Lampros Smyrnaios 88acaae20f - Replace the "numFullTextUrlsFound"-counter with "numFullTextsFound"-counter to reflect the end result of the actually available full-texts (which were downloaded by the Worker). 
- Optimize the gather-fileNames loop.
- Improve a message in "installAndRun.sh"
 2022-02-23 17:40:06 +02:00
Lampros Smyrnaios ad5dbdde9b - Improve performance when inserting records into the "attempt" table, by splitting the records equally, across more threads. 
- Bring back the "UriBuilder", which informs us in the logs, about the Controller's url (IP, PORT, API).

 2022-02-22 13:54:16 +02:00
Lampros Smyrnaios dfd40cb105 Insert only the records with uploaded-to-S3 full-texts, in the "payload" table. 2022-02-17 16:27:40 +02:00
Lampros Smyrnaios 71f6b46130 - In case of an error when creating the "current_assignment" table (e.g out of memory in the backend database server), check for partial-creation and drop it. Also, in any case, before we drop this table, now check if it exists firsts (in general it should always exist, unless the creation results in an error and the table was not created at all). 
- Fix an error-message.
- Update dependencies.
- Code cleanup.
 2022-02-14 12:36:00 +02:00

- Fix not giving the databaseName in the "ImpalaController.get10PublicationIdsTest()".
- Improve consistency in the "maxAttemptsPerRecord" value, among different threads. Also, reduce the value-increase by one.
- Check if the tableName string is empty, in the "mergeParquetFiles".

- Re-add the logback-spring configuration.
- Change the docker-app name.
 2022-02-04 15:49:56 +02:00
Lampros Smyrnaios 6aab1d242b - Improve performance when handling WorkerReports' database insertions, by using parallelism to insert to two different tables in the same time. Also, pre-cache the query-argument-types. 
- Update the error-message and counting system, on partial insertion event.
 2022-02-04 14:48:22 +02:00
Lampros Smyrnaios be4898e43e Bug fixes and improvements: 
- Fix an NPE, when the "getTestUrls"-endpoint is called. It was thrown because of an absent per-thread initialization of some thread-local variables.
- Fix JdbcTemplate error when querying the "getFileLocationForHashQuery".
- Fix the "S3ObjectStore.isLocationInStore" check.
- Fix not catching/handling some exceptions.
- Fix/improve log-messages.
- Optimize the "getFileLocationForHashQuery" to return only the first row. In the latest change, without this optimization, the query-result would cause non-handling the same-hash cases, because of an exception.
- Optimize the "ImpalaConnector.databaseLock.lock()" positioning.
- Update the "getTestUrls" api-path.
- Optimize list-allocation.
- Re-add the info-message about the successful emptying of the S3-bucket.
- Code cleanup.
