ElasticSearch ArrayIndexOutOfBoundsException

Hello,

I’m trying to use the ElasticSearch5-Rest Client to connect to an AWS ElasticSearch instance but I keep getting an exception when trying to start the workload.

Exception in thread "Thread-3" java.lang.ArrayIndexOutOfBoundsException: 1
	at com.yahoo.ycsb.db.elasticsearch5.ElasticsearchRestClient.init(ElasticsearchRestClient.java:87)
	at com.yahoo.ycsb.DBWrapper.init(DBWrapper.java:86)
	at com.yahoo.ycsb.ClientThread.run(ClientThread.java:91)
	at java.lang.Thread.run(Thread.java:748)

I’ve also tried with the regular ElasticSearch and ElasticSearch5 bindings. Any help would be much appreciated.

Thanks, Huy

@hngo4619 - What is the full command you used to launch?

Most likely you are not specifying es_host:es_port for your host list:

https://github.com/brianfrankcooper/YCSB/blob/master/elasticsearch5/src/main/java/com/yahoo/ycsb/db/elasticsearch5/ElasticsearchRestClient.java#L87

The elasticsearch5 binding readme describes the required format -https://github.com/brianfrankcooper/YCSB/tree/master/elasticsearch5

@risdenk Hi Risdenk, thank you for the assistance!

You were right, dumb mistake by me not specifying the port in the full host. I’m running into another error now if it’s not too much of a bother. I’m able to load/run a workload directly through the command line like so:

./bin/ycsb run elasticsearch5-rest -s -P workloads/workloadb -p exportfile=... -p path.home=... -p es.remote=true -p es.hosts.list=... -s -t

But when trying to launch a similar command through a Python script that runs the benchmark, I receive this error on trying to load and I’m not quite sure why I would get this error here as opposed to successfully on the command line:

Loading workload...

The load command as executed from the Python script:

Command line: -db com.yahoo.ycsb.db.elasticsearch5.ElasticsearchRestClient -s -P workloads/workloadb -P /root/YCSB/workload.dat -p es.index.key=ycsb_4krpny6ibdhad30m34gc -p es.remote=true -p es.hosts.list=... -p exportfile=output/run-transactions0.dat -s -threads 1 -t

==my use this code this ok . this Elasticsearch-5.5.0 ./bin/ycsb run elasticsearch5-rest -P workloads/workloada -p “es.hosts.list=172.18.3.120:9200,172.18.3.121:9200,172.18.3.122:9200”
