Rally errors


(Paul) #1

I am trying to get to grips with Rally;

I run with a command line of;

esrally --pipeline=benchmark-only --target-hosts=localhost:9200

It fails almost immediately with the following exception;

Writing additional logs to /database/benchmark/races/2016-06-02-15-32-27/vcloud/logs/rally_out.log

************** WARNING: A dark dungeon lies ahead of you **************


Rally dos not have control over the configuration of the benchmarked
Elasticsearch cluster.

Be aware that results may be misleading due to problems with the setup.
Rally is also not able to gather lots of metrics at all (like CPU usage
of the benchmarked cluster) or may even produce misleading metrics (like
the index size).


****** Use this pipeline only if you are aware of the tradeoffs. ******

Hi @paulkeogh,

Rally tries to create an index for the benchmark but your cluster does not support this mapping syntax. Which version of Elasticsearch are you trying to benchmark?

By the way, Rally's support is not really great at benchmarking the 1.x and 2.x versions of Elasticsearch but support for your scenario is coming in the next days.

By the way, the issue I was talking about is here: https://github.com/elastic/rally/issues/69

Hi,

Thanks for the reply.

I am using ES 2.3.3


(Daniel Mitterdorfer) #6

Hi @paulkeogh,

Thanks! I see that I can get a configuration for Elasticsearch 2.3 into the next release (I expect that it will be out this week).

Hi @paulkeogh,

I have released a new version of Rally. After the upgrade your benchmark should work fine now. If anything is not working as expected, please just post here and we'll figure it out.

Notes from my recent CentOS-7 experience YMMV

I needed to have a more recent version of git 2.x (currently can't get that from EPEL on CentOS7 as its version is ancient) to support the '-C' option.

So, I needed to compile git from source.

On that note, I also needed to install curl-devel prior to compiling git, and got the following error before figuring that out:

Cloning into '/home/deploy/.rally/benchmarks/tracks/default'...
fatal: Unable to find remote helper for 'https'
ERROR: Cannot run benchmark
Reason: Could not clone from 'https://github.com/elastic/rally-tracks' to '/home/deploy/.rally/benchmarks/tracks/default'

But, after installing curl-devel and recompiling git from src I was able to start esrally.

Hi @cmcc123,

oh that is too bad. Sorry that it was so much hassle to set up everything. I hope it is running smooth now.

Do you remember which version of git you had installed before? I checked the git changelog before I used "-C" in Rally and I thought it is safe because according to the changelog "-C" is supported since git 1.8.5.

Hi Daniel,
Unfortunately, it looks like our CentOS-7 / EPEL was sporting the ancient git version 1.8.3.1

cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

git --version
git version 1.8.3.1

Thanks


(Daniel Mitterdorfer) #11

Hi Chris,

thanks for your help and looking up the version. To be honest I fear the missing "-C" option was just the start and other git flags on which Rally is relying are probably missing too.

I see whether I can get git 1.8 installed on a machine and improve the compatibility or if I find blockers on the way I'll at least document the minimum required git version in the docs.
