Nitay Joffe updated HBASE-1515:
-------------------------------
Attachment: hbase-1515.patch
Yes, I agree with Ryan. In fact, if you look at the code currently we already
have the options hbase.regionserver.dns.interface/nameserver. These are used by
the info server that an RS brings up, yet the address is used by the RS itself.
Attaching a patch that fixes things, in particular:
# conf/hbase-default.xml:
## Remove 'hbase.regionserver', add 'hbase.regionserver.port'
# HConstants.java:
## Constants for changes above.
## Constant for master port to clean up use of string in various places.
# LocalHBaseCluster.java:
## Set port to 0 instead of entire address.
# HMaster.java:
## Cleanups of port constant and fix usage message.
# HRegionServer.java:
## Fold two constructors into one, like with HMaster.
## Lookup address to bind to using Hadoop style DNS query, just like HMaster.
## Remove bind option from main(), like we did with master.
# MiniHBaseCluster.java:
## Use constants for common master port string lookup.
# OOMERegionServer
## Remove unused constructor.
> Address part of config option hbase.regionserver unnecessary

> We have a configuration option "hbase.regionserver" that specifies address +
> port the region servers should bind to. I believe all of our users don't
> require the address part of it and always leave it as 0.0.0.0. Most people
> rsync their configs to all the machines in the cluster, so anything other
> than 0.0.0.0 doesn't really make sense.
> We should change this option into just hbase.regionserver.port, like we have
> with the master now.
