Steven Pine commented on ACCUMULO-601:
--------------------------------------
I think I found the problem. After turning on trace level logging I found that
the code (while hanging on the create command) was repeatedly
Indicating that "Found master at <host name only>:9999 and throwing a
"java.net.UnknownHostException: <host name only>
I don't believe my java code on the workstation is able to resolve <host name
only> to the fully qualified host name. Causing the hanging I am seeing.
My next questions are how do I get around this:
1. Is the entry I found in Zookeeper wrong as <host name only>:9999. Should it
be <Fully Qualified Hostname>:9999 ?
2. Is there something else I need to do?
3. What is the best approach to work around this issue (and what are the
implications if any)?
> Cannot create or delete tables via Java after upgrade to accumulo 1.4

> Key: ACCUMULO-601
> URL: https://issues.apache.org/jira/browse/ACCUMULO-601
> Project: Accumulo
> Issue Type: Bug
> Components: client
> Affects Versions: 1.4.0
> Environment: Cloud was upgraded from Cloudbase 1.3.4 to Accumulo
> 1.3.5 and then upgraded to accumulo 1.4.0. Hadoop version is 0.20.2r911707
> Reporter: Steven Pine
> Assignee: Billie Rinaldi
>
> After upgrade I am unable to create or delete a table via java using either
> the
> conn.tableOperations().delete(tableName);
> and/or
> conn.tableOperations().create(tableName);
> The error presents itself by hanging the code when it executes this line in
> the code.
> Important:
> Table scans via java are working fine.
> Table mutations via java also work fine.
> The same user account can create and deleted the table via accumulo shell.
> The cause of the code hanging cannot be determined further since there is
> nothing in the Eclipse logs or Server logs that provide any more information.
> I can verify that the connection to Zookeeper completes successfully...
> however there is no indication after that on the Server side that a call is
> being made to Accumulo to create/delete the table.
