Chris Nauroth updated HDFS-5201:
--------------------------------
Hadoop Flags: Reviewed
Thanks, Colin. This looks good. Just one very minor nit: can you please add a
JavaDoc {{@return}} tag on {{NativeIO#getMemlockLimit}}?
+1 for the patch after that.
> NativeIO: consolidate getrlimit into NativeIO#getMemlockLimit
> -------------------------------------------------------------
>
> Key: HDFS-5201
> URL: https://issues.apache.org/jira/browse/HDFS-5201
> Project: Hadoop HDFS
> Issue Type: Sub-task
> Components: datanode
> Affects Versions: HDFS-4949
> Reporter: Colin Patrick McCabe
> Assignee: Colin Patrick McCabe
> Attachments: HDFS-5201-caching.001.patch
>
>
> Let's consolidate {{NativeIO#POSIX#getrlimit}} into
> {{NativeIO#getMemlockLimit}}. This avoids a few issues with the current
> function: it is not available on Windows, it relied on Linux-specific
> constants, and it currently returns a string which has to be parsed rather
> than a long.
