Subject [jira] [Created] (HBASE-10200) Better error message when HttpServer fails to start due to java.net.BindException
Date Wed, 18 Dec 2013 18:49:10 GMT
Ted Yu created HBASE-10200:
------------------------------

             Summary: Better error message when HttpServer fails to start due to java.net.BindException
                 Key: HBASE-10200
                 URL: https://issues.apache.org/jira/browse/HBASE-10200
             Project: HBase
          Issue Type: Task
            Reporter: Ted Yu
            Priority: Minor


Starting HBase using Hoya, I saw the following in log:
{code}
2013-12-17 21:49:06,758 INFO  [master:hor12n19:42587] http.HttpServer: HttpServer.start()
threw a non Bind IOException
java.net.BindException: Port in use: hor12n14.gq1.ygridcore.net:12432

        at java.lang.Thread.run(Thread.java:722)
Caused by: java.net.BindException: Cannot assign requested address

        at org.apache.hadoop.http.HttpServer.openListener(HttpServer.java:738)
{code}
This was due to hbase.master.info.bindAddress giving static address but Hoya allocates master
dynamically.

Better error message should be provided: when bindAddress points another host than local host,
message should remind user to remove / adjust hbase.master.info.bindAddress config param from
hbase-site.xml
