Fengdong Yu commented on HBASE-8211:
------------------------------------
Himanshu,
Thanks for comments.
<blockquote>The idea of HA support is that a client doesn't need to change any
url whatsoever, otherwise its not really a failover. </blockquote>
yes. I read the code again. that's it.
<blockquote>If you mean a change in their value because of failover, then it is
not required.</blockquote>
for HDFS HA, fs.defaultFS should be configured such as
<value>hdfs://mycluster</value>, so for hbase.rootdir, can we configured such
as: <value>hdfs://mycluster/hbase</value>
currently, we just using a specified name node address for hbase.rootdit.
> Support for NN HA for 0.94
