Hello, We have a fair amount of code that uses IMetaStoreClient implementation to talk over a network to Hive metastore instances. I was under the impression that the recommended way to create said clients was to use:
org.apache.hive.hcatalog.common.HCatUtil.getHiveClient(HiveConf) However, I'm keen that our clients retry in the event of adverse network conditions and I've recently discovered that clients constructed in this manner do not appear to be of the retrying variety. In fact it seems as though only the following factory method creates clients of this type: org.apache.hadoop.hive.ql.metadata.Hive.getMSC() But, in my particular use case I wish to copy data between two metastores and this class seems to do a bunch of ThreadLocal stuff that would appear to make it awkward to instantiate multiple, different IMetaStoreClient instances. Therefore I think I'll need to instead call the following directly: org.apache.hadoop.hive.metastore.RetryingMetaStoreClient.getProxy(HiveConf, HiveMetaHookLoader, String) I'd be grateful for any advice regarding how I best create multiple, robust clients that can collaborate in a single thread. Thanks, Elliot.
