Subject [jira] [Commented] (HDFS-8134) Using OpenJDK on HDFS
Date Tue, 14 Apr 2015 21:20:59 GMT

Steve Loughran commented on HDFS-8134:
--------------------------------------

Actually, where hadoop is weak is that nobody tests it on the preview releases of openjdk.
If someone where to volunteer to test against the pre-release openjdk 8 and openjdk 9, that
would actually be of benefit

> Dear All,
> We would like to start the effort of certifying OpenJDK with HDFS. The effort includes
compiling HDFS source code with OpenJDK and reporting issues if there is any, and completing
performance study and comparing all the results with Oracle JDK. The workload we will start
with is DFSIOe which is part of the HiBench suite. We can surely add more workloads such as
Teragen and etc. into our testing environment if there is any interest from this community.

> This is our first time to work on this community. Please do let us know your feedback
and comments. If you all like the idea and this is the right place to start the effort, we
will be sending out the data soon!
> Thanks,
> Yingqi
