Store hbase-site.xml in ZooKeeper
---------------------------------
Key: HBASE-1154
URL: https://issues.apache.org/jira/browse/HBASE-1154
Project: Hadoop HBase
Issue Type: Improvement
Affects Versions: 0.19.0
Environment: All
Reporter: ryan rawson
Fix For: 0.21.0
Right now hbase-site.xml is stored in the classpath of every individual
machine. To update parameters of the cluster, one has to copy files to every
cluster machine then restart the daemons.
Instead of storing config files in a local disk, store them in Zoo Keeper.
Regionservers can then put a watch on the file, and do something appropriate
when the config changes. Restarting en-masse is probably not the best solution
however.
A similiar change could be done for HDFS/Hadoop for their own hadoop-site.xml
file. That is a little out of scope :-)
