ATTACHMENT ID: 12979845 - PreCommit-HIVE-Build
> ClassCastException when initializing HiveMetaStoreClient on JDK10 or newer
> --------------------------------------------------------------------------
>
> Key: HIVE-21508
> URL: https://issues.apache.org/jira/browse/HIVE-21508
> Project: Hive
> Issue Type: Bug
> Components: Clients
> Affects Versions: 3.2.0, 2.3.4
> Reporter: Adar Dembo
> Assignee: Ana Jalba
> Priority: Major
> Fix For: 4.0.0, 2.3.7
>
> Attachments: HIVE-21508.1.branch-2.3.patch, HIVE-21508.patch
>
>
> There's this block of code in {{HiveMetaStoreClient:resolveUris}} (called
> from the constructor) on master:
> {noformat}
> private URI metastoreUris[];
> ...
> if (MetastoreConf.getVar(conf,
> ConfVars.THRIFT_URI_SELECTION).equalsIgnoreCase("RANDOM")) {
> List uriList = Arrays.asList(metastoreUris);
> Collections.shuffle(uriList);
> metastoreUris = (URI[]) uriList.toArray();
> }
> {noformat}
> The cast to {{URI[]}} throws a {{ClassCastException}} beginning with JDK 10,
> possibly with JDK 9 as well. Note that {{THRIFT_URI_SELECTION}} defaults to
> {{RANDOM}} so this should affect anyone who creates a
> {{HiveMetaStoreClient}}. On master this can be overridden with {{SEQUENTIAL}}
> to avoid the broken case; I'm working against 2.3.4 where there's no such
> workaround.
> [Here's|https://stackoverflow.com/questions/51372788/array-cast-java-8-vs-java-9]
> a StackOverflow post that explains the issue in more detail. Interestingly,
> the author described the issue in the context of the HMS; not sure why there
> was no follow up with a Hive bug report.
