[jira] [Updated] (AMBARI-14076) Stack Upgrade: ExecuteStage class
to support a list of Tasks as opposed to a single one
[ https://issues.apache.org/jira/browse/AMBARI-14076?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Alejandro Fernandez updated AMBARI-14076:
-----------------------------------------
Description:
We have a limitation today in the Upgrade Packs used for NonRolling (Express) Upgrade in which the ExecteStage class can only have a single Task, and this results in a lot of repetition and verbose packs.
E.g.,
{code}
<!--HBASE-->
<execute-stage service="HBASE" component="HBASE_MASTER" title="Apply config changes for HBase Master">
<task xsi:type="configure" id="hdp_2_3_0_0_hbase_master_set_global_memstore_size"/>
</execute-stage>
<execute-stage service="HBASE" component="HBASE_MASTER" title="Calculating HBase Properties">
<task xsi:type="server_action" summary="Calculating HBase Properties" class="org.apache.ambari.server.serveraction.upgrades.HBaseConfigCalculation" />
</execute-stage>
<execute-stage service="HBASE" component="HBASE_MASTER" title="Apply config changes for HBase Master">
<task xsi:type="configure" id="hdp_2_3_0_0_hbase_master_adjust_authorization_coprocessors"/>
</execute-stage>
{code}
Instead, a single ExecuteStage should have all of the tasks.
The ExecuteStage class is inside ClusterGrouping.java
