janusgraph创建索引报错

创建名为byTelComposite的索引，installed转registered时报错：

janusgraph>GraphIndexStatusReport[success=false, indexName='byTelComposite', targetStatus=[REGISTERED], notConverged={tel=INSTALLED}, converged={}, elapsed=PT1M0.261S]

原因：
出现了多个事务或者实例

解决：
关闭实例过程

gremlin> mgmt = graph.openManagement()
==>[email protected]7c75
//查询实例
gremlin> mgmt.getOpenInstances()
==>c0a81433160396-s11(current)
==>c0a81433160854-s13
==>c0a81433160854-s11
==>c0a81433160854-s15
//出现多个则关闭
gremlin> mgmt.forceCloseInstance('c0a81433160854-s11')
==>null
gremlin> mgmt.commit()
==>null

关闭事务过程

//查询事务
graph.getOpenTransactions()//打开多个事务
//关闭事务
graph.getOpenTransactions().getAt(0).rollback()  //关闭
或者
int size = graph.getOpenTransactions().size();for(i=0;i<size;i++) {graph.getOpenTransactions().getAt(0).rollback()}  //size替换为事务的数量

最后查看实例事务是否都关闭

mgmt = graph.openManagement()
mgmt.getOpenInstances()
mgmt.commit()    
graph.getOpenTransactions()

INSTALLED转REGISTERED方法：
执行 REGISTER_INDEX ACTION，使索引状态INSTALLED 转为 REGISTERED

mgmt = graph.openManagement()
mgmt.updateIndex(m.getGraphIndex('byTelComposite'), SchemaAction.REGISTER_INDEX).get()
mgmt.commit()

或者

ManagementSystem.awaitGraphIndexStatus(graph, 'byTelComposite').call()

直接查看索引的状态

mgmt = graph.openManagement()
index = mgmt.getGraphIndex('byTelComposite')
index.getIndexStatus(mgmt.getPropertyKey('tel'))
