60010 on master and port 60030 on regionservers --- these prots are used
for http request where hadoop runs a http server for giving you Web UI for
hadoop 50070, hbase 60010 and region servers 60030. can try to open this
address in your browser like
http://hadoopnamenode:60010 -- HMaster WebUI
and will understand what it is for.

Hi all. I'm doing a project for my university so that i have to know
perfectly how all the Hbase ports work. Studing the documentation i
found
that Zookeeper accept connection on port 2181, Hbase master on port
6
and Hbase regionservers on port 60020. I didn't understand the
importance
of port 60010 on master and port 60030 on regionservers. Can i not use
them?
From the documentation (http://hbase.apache.org/book.html#config.files):
hbase.regionserver.info.port
The port for the HBase RegionServer web UI Set to -1 if you do not want
the
RegionServer UI to run.
Default: 60030
You can look for the other port in there too.
More important: if i launch Hbase in pseudo-distribuited mode, running
all
processes on localhost, what ports are used for each of the processes
if
i
launch 1, 2, 3 or more backup masters and if i launch few regionservers
(less than 10) or a lot of regionservers (10, 20, 100)?
It'll clash, you'll have to have different hbase-site.xml for each
process
you want to start.
you can get away with just using 0 as the port numbers and let the nodes
sort it out for themseves, though fixing the master web ui port is useful
if you want to bookmark it and avoid playing with netstat, jps and lsof to
work out which port a given process is listening on
