Release version 0.12.0

[risdenk]

This release is a bit overdue. There hasn't been much activity in the past few weeks as far as things being merged. I plan to cut the staging branch on Wednesday afternoon ~36hrs from now.

I'll also publish the change list going into this release and put out a request for volunteers to test it.

With next week being Thanksgiving in the US, that gives the Thursday/Friday this week and a few days next week for testing. If testing goes well we can release around 12/1.

[shivam-maharshi]

@risdenk While running this command: {fullpath}/bin/ycsb.bat run rest -s -P workloads/workload_rest, I received the error below:

Exception in thread "main" java.lang.NoClassDefFoundError: org/apache/htrace/core/HTraceConfiguration
        at com.yahoo.ycsb.Client.main(Client.java:947)

Any suggestions?

[risdenk]

@shivam-maharshi hmmm I see the same with

./bin/ycsb.sh run rest -s -P ./rest/src/test/resources/workload_rest

I don't get an error when I try with:

./bin/ycsb run rest -s -P ./rest/src/test/resources/workload_rest

Looks like there might be an issue with ycsb.sh and ycsb.bat resolving the classpath.

[risdenk]

@shivam-maharshi the issue is that the core module dependencies aren't included in a source checkout when using ycsb.sh or ycsb.bat. There isn't a lib or dependency directory for the core module after packaging. It should work if you build YCSB and extract a distribution.

[yuyantingzero]

googledatastore looks good, thanks!

[risdenk]

Thanks @yuyantingzero for testing googledatastore!

[risdenk]

@shivam-maharshi - Any update on testing the rest binding?
@xiangcong - Can you check the azuretablestorage binding?
@Laa - Can you check the orientdb binding?

[risdenk]

Since the testing hasn't been completed yet, going to push out testing deadline to 12/5. Then release next week if possible.

[joshelser]

@risdenk JDBC looks fine to me. Poked around with MySQL and Apache Phoenix. Thanks for putting the RC together!
