[jira] [Comment Edited] (HBASE-20690) Moving table to target
rsgroup needs to handle TableStateNotFoundException
[ https://issues.apache.org/jira/browse/HBASE-20690?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16776326#comment-16776326 ]

------------------------------------------------------------
Tried with patch v002 and could see a NPE in master's log, thrown from the following statement:
{code}
String groupName =
master.getClusterSchema().getNamespace(desc.getTableName().getNamespaceAsString())
.getConfigurationValue(RSGroupInfo.NAMESPACE_DESC_PROP_GROUP);
{code}
master.ClusterSchema() is null and I guess the the cause is that cluster schema service is not initialized yet
