Subject [jira] [Commented] (ACCUMULO-601) Cannot create or delete tables via Java after upgrade to accumulo 1.4
Date Fri, 25 May 2012 12:36:23 GMT

    [ https://issues.apache.org/jira/browse/ACCUMULO-601?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13283344#comment-13283344

Adam Fuchs commented on ACCUMULO-601:
-------------------------------------

We've also had some success getting around this issue in the past by setting the domain name
on all the nodes (using domainname).

The RSA message is because your ssh known hosts database doesn't have a mapping for the FQDN.
The start-all.sh script uses ssh to launch processes.

Unfortunately, there are many ways to set up DNS and Linux networking, and most of them usually
work for most applications. Accumulo should probably be more robust and work with a broader
set of common linux networking configurations.

>             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

> 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.
