ATTACHMENT ID: 12980090 - 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.patch, HIVE-21508.2.branch-2.3.patch, > HIVE-21508.3.branch-2.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.
