--------------------------------------------
Summary: Stack Upgrade: ExecuteStage class to support a list of
Tasks as opposed to a single one
Key: AMBARI-14076
URL: https://issues.apache.org/jira/browse/AMBARI-14076
Project: Ambari
Issue Type: Story
Components: ambari-server
Affects Versions: 2.2.0
Reporter: Alejandro Fernandez
Assignee: Alejandro Fernandez
Fix For: 2.2.0
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}
The ExecuteStage class is inside ClusterGrouping.java
