{: #unsupported-operations}
The following functionality is not supported in {{site.data.keyword.iae_full_notm}}.
{: #ae1.1-deprecation}
The AE 1.1 software packages based on Hortonworks Data Platform (HDP) 2.6.5 are deprecated. You can no longer provision new instances of {{site.data.keyword.iae_full_notm}} with the AE 1.1 software packages. Although you can still work on the AE 1.1 clusters you have created, you can't resize those clusters and add additional nodes.
Although all existing AE 1.1 clusters will only be deleted after December 31, 2019, you should stop using those clusters now and start creating new AE 1.2 clusters as described in Best practices.
{: #ae1.0-deprecation}
The AE 1.0 software packages based on Hortonworks Data Platform (HDP) 2.6.2 are deprecated. You can no longer provision new instances of {{site.data.keyword.iae_full_notm}} with the AE 1.0 software packages. Although you can still work on the AE 1.0 clusters you have created, you can't resize those clusters and add additional nodes.
Although all existing AE 1.0 clusters will only be deleted after September 30, 2019, you should stop using those clusters now and start creating new AE 1.2 clusters as described in Best practices.
{: #ae1.2-hive-llap}
Currently, you can't resize a cluster created using the AE 1.2 Hive LLAP software package. You need to plan your cluster size before you create the cluster and specify the required number of nodes at the time you provision the {{site.data.keyword.iae_full_notm}} service instance.
{: #ae-all-centos-repo}
The package-admin tool can only install software packages from the centOS repository.
For security reasons, you should use the package-admin tool to install, update, or remove operating system packages from the centOS repository.
{: #os-oackages-lost}
OS packages that are installed through the package-admin tool are not persisted if the host machine is rebooted. These packages need to be installed again.
{: #hive-view-not-supported}
Hive View has been removed from the underlying platform in AE 1.2. You can use any other JDBC UI based client such as SQuirrel SQL or Eclipse Data Source Explorer as an alternative.
{: #hive-spark-not-same-metastore}
From AE 1.2 onwards, Hive and Spark do not share the same metastore. This is by design in the underlying engine.
To override this behavior:
- In the Ambari UI, navigate to Ambari > Spark2 > Config > spark2-hive-site-override.
- Set
"metastore.catalog.default" : "hive".
Refer to the following links to understand the reasoning and repercussions for the change:
- Hive Warehouse Connector for accessing Apache Spark data{: external}
- Using the Hive Warehouse Connector with Spark{: external}
The only way to configure a cluster to work with PostgreSQL is either through the UI or by using adhoc customization. See Using an adhoc PostgreSQL customization script.
Configuring the cluster at the time the cluster is created by using bootstrap customization is not supported because it requires the PostgreSQL certificate to be present on the mn002 node before the Hive service is started. However the bootstrap script is only executed after the cluster was created. The same applies to using advanced provision options described here. There is no way to download the certificate prior to cluster creation.
