Hi All,
We've done quite a bit of Accumulo on AWS.
The first problem you see is that the users can't be created if HDFS is
not up on time. We've seen this more often when creating the trace user
rather than root.
If you can post output from the script, that would be helpful.

Hi there,
I was going to do some performance tests to evaluate the technology on
AWS.
Followed
https://blogs.aws.amazon.com/bigdata/post/Tx15973X6QHUM43/Running-Apache-Accumulo-on-Amazon-EMR
The exact command I am using:
aws emr create-cluster --name Accumulo --no-auto-terminate
--bootstrap-actions
Path=s3://elasticmapreduce.bootstrapactions/accumulo/1.6.1/install-accumulo_mj,Name=Install_Accumulo
--ami-version 3.3.1 --instance-groups
InstanceGroupType=MASTER,InstanceCount=1,InstanceType=m3.xlarge
InstanceGroupType=CORE,InstanceCount=3,InstanceType=m3.xlarge
--ec2-attributes KeyName=elastic_search_test --use-default-roles
After that I can access monitor web-interface and see that everything
good, however I am not able to access shell with root/secret and any
other possible combination. I receive – “Invalid credentials”. What is
really interesting – 1 attempt out of 10 was successful and everything
worked as expected. This fact really confuses me.
./stop-all.sh does not work without ctrl+c
When I do ./start-all.sh I can see many logs similar to the below.
Script that is used behind the scenes is this one:
https://github.com/awslabs/emr-bootstrap-actions/blob/master/accumulo/1.6.1/install-accumulo_mj
Any idea why I observe this behaviour?
Many thanks,
Roman
