[jira] [Updated] (HIVE-10010) Alter table results in NPE [hbase-metastore branch]

["Alan Gates (JIRA)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HIVE-10010?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Alan Gates updated HIVE-10010:
------------------------------
    Attachment: HIVE-10010.patch

This patch completely reworks SharedStorageDescriptor.  It is now much simpler.  Rather than having a pointer to an actual shared object, it does a shallow copy of the StorageDescriptor it is handed.  Then if a user does a get on a nested structure or list, that structure or list is deep copied.  That way if the user modified the structure or list the modifications apply only to current StorageDescriptor, not to all of the SharedStorageDescriptors that are sharing the nested structures and lists.
