Steven Pine commented on ACCUMULO-601:
--------------------------------------
I wanted to pass on my further testing for completness.
I still have not been able to resolve this problem. It still hangs during the
create or delete from my workstation it doesn't matter whether I run this
inside eclipse or from the command line.
I Tested the following:
Server Side (Linux):
1. Ran my java source code on the Server and it works.
2. I Generated a jar via Eclipse (after dumb-ing it down to 1.6 jre) and it
also ran fine on the Server.
Workstation side (Windows):
1. Running the java source via Eclipse hangs at the create line of the code.
2. Running the jar from the Windows command line also hangs at the create line.
Note: I re-copied the jar files from the server to the Workstation just to
ensure that I was running with the exact same jar files.
This narrows down my ideas to two possibilities:
1. Some Firewall rule is intercepting traffic so that it hangs and never
completes (however I can Scan and perform mutation on tables from my
workstation).
2. There is some kind of dependency be it Linux or some object on the Server
that the create/delete class depends on that is not there in Windows.
Note: Keeping in mind that I can run java code to scan and perform mutations
against Accumulo tables and they work fine from within Eclipse (on my
Workstation)leads me to lean more towards option 2 (unless there is some
specific traffic that occurs when creating/deleting tables that does not occur
when you scan or perform mutations).
> 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.
