Subject Re: HDFS name node HA roadmap
Date Fri, 19 Jun 2009 16:23:59 GMT
Hi Andrew,

Yes, our IBM is implementing HA for Hadoop which will be open sourced 
soon. I think shv from Yahoo also post JIRA to describe this issue.

However, our approach may be different with shv. Let me discuss with shv 
about how to combine our thoughts and implementation together. 

True insight comes from within!

Please respond to


HDFS name node HA roadmap


My understanding is that the HDFS name node single point of failure will
be removed in Hadoop 0.21. Is that still the case? Also, what is the
expected delivery date of that release?
