    Resolution: Not a Problem


> Unhelpful exception from Client on HBase master startup when hbase.rootdir is incorrect.
> ----------------------------------------------------------------------------------------
>                 Key: HBASE-2826
>                 URL: https://issues.apache.org/jira/browse/HBASE-2826
>             Project: HBase
>          Issue Type: Improvement
>          Components: IPC/RPC
>    Affects Versions: 0.90.0
>         Environment: Ubuntu Karmic, using Cloudera distribution karmic-cdh3. The exact
hbase version is 0.89.20100621+17.
>            Reporter: James Cockrill
>            Priority: Minor
> As per users@hbase.apache.org thread: http://mail-archives.apache.org/mod_mbox/hbase-user/201007.mbox/%3CAANLkTimyCtWiuNxWw9P2IFAy6Y4Q7X8oLZSZNdggV3Nn@mail.gmail.com%3E
> I setup HBase (and as such, Zookeeper) on Ubuntu Karmic using the Cloudera Karmic CDH3
distribution. Zookeeper has installed fine, however when it comes to starting an hbase master,
it falls over with the following exception:
> (stack trace summarised to last bit)
> Caused by: java.io.EOFException
>    at java.io.DataInputStream.readInt(DataInputStream.java:375)
>    at org.apache.hadoop.ipc.Client$Connection.receiveResponse(Client.java:508)
>    at org.apache.hadoop.ipc.Client$Connection.run(Client.java:446)
> The cause was that the hbase.rootdir was incorrectly set to hdfs://master:50071/hbase,
when it should have been set to port 50070. After remedying this hbase master started fine.
> I was asked to raise this as a JIRA to investigate the possibility of improving the handling
of the EOFException to perhaps indicate more clearly to the user that an incorrect address
has been specified for the rootdir, rather than the very unclear statement above.
