Description

For TestMetastoreEndToEnd, If metastore didn't finish the initialization. context.getMetaStoreClient will throw exception.

HiveMetaStoreClient client = context.getMetaStoreClient(ADMIN1);

We should wait for the initialization of metastore, for example:

    HiveMetaStoreClient client = null;
    for (int i=0; i < 10; i++) {
      try {
        client = context.getMetaStoreClient(ADMIN1);
        break;
      } catch (Throwable e) {
        // ignore
      }
      Thread.sleep(6000);
    }
