Hello:
I'm using titan with hbase and elasticsearch, all was ok at first, but yesterday when I was searching as usual, it worn
Could not find a suitable index to answer graph query and graph scans are disabled: [( contents = hdfs)]: EDGE
like below:
gremlin> index=mgmt.getGraphIndex('message')
==>message
gremlin> index.getIndexStatus(mgmt.getPropertyKey('contents')
==>ENABLED
gremlin> g.E().has('contents','hdfs').values()
Could not find a suitable index to answer graph query and graph scans are disabled: [( contents = hdfs)]: EDGE
the index was a mixed type index, using elasticsearch backhand
this is very strange, because in fact the index does exist, and before today, all queries alike this was ok.
and when data inserts into the database, I could see the increase of indexed data num by using elasticsearch count API
and the flowing query is ok
gremlin> graph.indexQuery("message","e.contents: hdfs").edges()
Anyone have any idea about this problem?
Thanks!
