> HiveCatalog should set HiveConf.hiveSiteLocation back
> -----------------------------------------------------
>
> Key: FLINK-36594
> URL: https://issues.apache.org/jira/browse/FLINK-36594
> Project: Flink
> Issue Type: Bug
> Components: Connectors / Hive
> Affects Versions: 1.20.1
> Reporter: slankka
> Priority: Minor
> Labels: pull-request-available
>
> recently, I'm using Hudi sync to HMS, when using HiveCatalog, HiveCatalog
> changes HiveConf.hiveSiteLocation to null, which will cause Hudi cannot get
> hive-site conf provided in classpath. I found the root cause is HiveCatalog
> changes the HiveConf.
> HiveCatalog can load hive-site.xml itself without this variable , but the
> rest code after that, is still assuming HiveConf 'searches' hive-site.xml
> from classpath.
> I mean, HiveCatalog turn it off, then any instance of HiveConf will never
> load hive-site.xml which user put it on classpath, yarn provided, such as
> hudi, only if you addResource explicitly, or Hive search it from user uber
> jar which need another effort.
>
> Example
> {code:java}
> //at first
> HiveConf static initialization code try to search hive-site.xml, and only
> once.
> static {
> hiveSiteURL = findConfigFile(classLoader, "hive-site.xml", true);
> }{code}
>
> {code:java}
> String name = "myhive";
> String defaultDatabase = "mydatabase";
> String hiveConfDir = "/opt/hive-conf";
> HiveCatalog hive = new HiveCatalog(name, defaultDatabase, hiveConfDir);
> tableEnv.registerCatalog("myhive", hive);
> // set the HiveCatalog as the current catalog of the session
> tableEnv.useCatalog("myhive"); {code}
> after running code above:
> {code:java}
> //Another framework who are using hive
> HiveConf hiveConf = new HiveConf(hadoopConf, HiveConf.class); {code}
> The hiveConf DOES NOT load hive-site.xml from classpath, which will cause
> configuration loading failure.
