Description

NullPointerException might occur if table.getParameters() returns null when method isNonNativeTable is invoked in class MetaStoreUtils.

public static boolean isNonNativeTable(Table table) {
    if (table == null) {
      return false;
    }
    return (table.getParameters().get(hive_metastoreConstants.META_TABLE_STORAGE) != null);
  }

This will cause a stack trace without any suggestive information at client:
