Chris Nauroth updated HDFS-5202:
--------------------------------
Description: HDFS caching currently is implemented using POSIX syscalls for
checking ulimit and locking pages of memory into the process's address space.
These POSIX syscalls do not exist on Windows. This issue will implement
equivalent functionality so that Windows deployments can use Centralized Cache
Management. (was: This is an umbrella JIRA for adding Windows support for HDFS
caching.)
Summary: Support Centralized Cache Management on Windows. (was:
umbrella JIRA for Windows support in HDFS caching)
I've changed the summary and description to remove the word "umbrella". This
patch is actually going to be quite small, and the word "umbrella" just seemed
ominous. :-)
