> For {{TestMetastoreEndToEnd}}, If metastore didn't finish the initialization.  context.getMetaStoreClient will throw exception. 
> {noformat}
> HiveMetaStoreClient client = context.getMetaStoreClient(ADMIN1);
> {noformat}
> We should wait for the initialization of metastore, for example:
> {noformat}
>     HiveMetaStoreClient client = null;
>     for (int i=0; i < 10; i++) {
>       try {
>         client = context.getMetaStoreClient(ADMIN1);
>         break;
>       } catch (Throwable e) {
>         // ignore

>       Thread.sleep(6000);
