Framework Changes

Platform specific launching scripts

This release includes a first-pass implementation of Windows and Posix specific launching scripts for YCSB. They can be found along side the normal python script in the bin directory. Downstream users are encouraged to begin testing use of these scripts, since the Python bin\ycsb is expected to be removed in a future version. (#737, #777, #784)

Other Changes

  • #751 [core] correct calculation of weighted histograms

Packaging Changes

Cassandra2 module included in convenience artifacts

The prebuilt artifact should include the cassandra2 module again. See #766.

Running from source on Windows

The known issue "Running directly from a source checkout on Windows is not supported. (see #335)" should now be solved, so long as downstream users rely on the Windows-specific YCSB launcher bin/ycsb.bat. See #737 and #777

Thanks

Special thanks for helping to test this release goes out to: @allanbank, @cmatser, @daschl, @jaemyoun, and @sekikn!
