HMaster sends duplicate ports to regionserver in HServerAddress
---------------------------------------------------------------
Key: HBASE-3425
URL: https://issues.apache.org/jira/browse/HBASE-3425
Project: HBase
Issue Type: Bug
Components: master
Affects Versions: 0.90.0
Reporter: Matt Corgan
Fix For: 0.90.0
On regionserver startup, the regionserver receives an HServerAddress from the
master as a Writable. It's a string hostname and an integer port. Our master
is also appending the port to the string, so when they are concatenated it
becomes hadoopnode98:60020:60020 and the HServerAddress cannot be instantiated.
This should probably be fixed in the master as well, but I don't know where it
happens. The attached patch handles it in the regionserver.
