Alan Burlison commented on HADOOP-11985:
----------------------------------------
Some other Solaris-related issues, already fixed:
HADOOP-11403 Avoid using sys_errlist on Solaris, which lacks support for it
HADOOP-11466 FastByteComparisons: do not use UNSAFE_COMPARER on the SPARC
architecture because it is slower there
The current fix for this just disables the optimised version of the code.
That's unlikely to be a good solution, use of JNI to call the platform's
optimised memory comparison routine (memcmp) should be investigated.
> Improve Solaris support in Hadoop
> ---------------------------------
>
> Key: HADOOP-11985
> URL: https://issues.apache.org/jira/browse/HADOOP-11985
> Project: Hadoop Common
> Issue Type: New Feature
> Components: build, conf
> Affects Versions: 2.7.0
> Environment: Solaris x86, Solaris sparc
> Reporter: Alan Burlison
> Assignee: Alan Burlison
> Labels: solaris
>
> At present the Hadoop native components aren't fully supported on Solaris
> primarily due to differences between Linux and Solaris. This top-level task
> will be used to group together both existing and new issues related to this
> work. A second goal is to improve Hadoop performance on Solaris wherever
> possible.
> Steve Loughran suggested a top-level JIRA was the best way to manage the work.
