Does this fix the problem? Is it something others running 0.20 should pull in?

[jira] Resolved: (HBASE-3186) Patch that disables pread
Posted by "stack (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-3186?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
stack resolved HBASE-3186.
--------------------------
Resolution: Not A Problem
Mozilla problem had to do with bad NIC driver. Hopefully pread is about to get less dumb (hdfs-941). Closing in meantime as 'Not a problem'.
