我正在尝试使用以下代码通过 Oozie Java Action 连接到 Posgres Hive Metastore。
我将 hive-site.xml 传递给操作，因此它应该具有所需的所有信息。
HiveMetaStoreClient client = new HiveMetaStoreClient(conf);
log.info("Successfully created the HiveMetaStoreClient");
try {
log.info(String.format("Loading the partitions for %s.%s", database, table));
List<Partition> partitions = client.listPartitions(database, table, (short) 200);
log.info(String.format("Processing %d partitions", partitions.size()));
for (Partition partition : partitions) {
StorageDescriptor sd = partition.getSd();
String location = sd.getLocation();
String newLocation = location.replace(from, to);
log.info(String.format("Moving from %s to %s", location, newLocation));
sd.setLocation(newLocation);
}
} catch (TException e) {
logExceptionStack(e);
}
该日志并不完全错误，但它表明它正在查看其他带有 DERBY 后端的元存储；
我不知道在哪里寻找问题并强制HiveMetaStoreClient指向正确的元存储。
