本文介绍了Janusgraph 0.3.2+HBase 1.4.9-无法设置图形。时间戳的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我在码头容器中运行Janusgraph 0.3.2，并尝试使用运行HBase 1.4.9的AWS EMR集群作为存储后端。我可以运行gremlin-server.sh，但是如果我试图保存一些内容，我会得到下面粘贴的堆栈跟踪。在我看来，这些锁是使用不同的时间戳长度创建的，导致它看起来不存在锁。

我尝试将raph.timeStamp设置添加到配置文件，但仍然出现相同的错误。

这是我的配置 gremlin-server.yml

host: 0.0.0.0
port: 8182
scriptEvaluationTimeout: 30000
channelizer: org.apache.tinkerpop.gremlin.server.channel.WsAndHttpChannelizer
graphs: {
  graph: conf/gremlin-server/janusgraph-hbase-server.properties
}
... more ...

janusgraph-hbase-server.properties

gremlin.graph=org.janusgraph.core.JanusGraphFactory
storage.backend=hbase
storage.hostname=${HBASE_HOSTNAME}
storage.port=2181

cache.db-cache = true
cache.db-cache-clean-wait = 20
cache.db-cache-time = 180000
cache.db-cache-size = 0.5

graph.timestamps=MILLI

注意：我认为由于堆栈跟踪中显示的时间戳不匹配，所以raph.timeStamp=Milli可以解决这个问题。ZooKeeper仅在HBase主服务器上运行，因此HBase_hostname将填写在HBase主服务器的fqdn中。

Could not commit transaction due to exception during persistence

推荐答案

我遇到了这个问题，因为我面临着类似的问题。 正如本帖所言：Janusgraph JanusGraphException Could not commit transaction due to exception during persistence 我们应该将raph.timeStamp属性值设置为Nano。 我不太了解这是如何工作的。

这篇关于Janusgraph 0.3.2+HBase 1.4.9-无法设置图形。时间戳的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
