Thanks a lot!
I'm sorry I wasn't available these days for more input. But you've
concluded yourself all I could have told you :)

Neda,
You have discovered a nasty bug in the controller. I was able to
reproduce it in a test using the minicluster and I working to resolve the
bug. Thanks for info!

Neda,
I'm sorry, I just realized that I pointed you to that version in you last
email. So you are likely on 0.2.2.
I see that a NPE can occur on line 1083 on the controller.

I will take a look at this and try to recreate the problem. I bet that
it's a race problem after dropping and then creating a new table. If you
put a sleep for a few seconds after creating the table does it still occur?
Thanks for the information on the bug. Sorry for the earlier response, I
should have looked at the stack trace more closely.

What version are you running? If it's the 0.2.0 release then it has a
series of know bugs related to table name reuse. Truncate is basically
dropping a table by it's name and recreating it. The bugs are related to a
table name being reused. I would suggest that you run 0.2.2 which has not
been released yet. It is code complete and has the the fixes for this
problem.
I would suggest that you run code from the apache-blur-0.2 branch. The
version will be 0.2.2 when released.
To check it out and compile yourself:
git clone https://git-wip-us.apache.org/repos/asf/incubator-blur.git
git checkout apache-blur-0.2
mvn install -DskipTests -Dhadoop1

Hi!
I've been trying to truncate table from my code.
I did succeed in that, but if I try to add some data to it afterwards,
I get NullPointerException at
stackTraceStr:java.lang.NullPointerException
at org.apache.blur.thrift.BlurControllerServer.mutate(
BlurControllerServer.java:1083)

While truncating table, I tried fetching its descriptor before and
using it afterwards when recreating, but same error.
As far as I've seen, only restarting shard server helped. I'm using
only one shard server when testing.
Any ideas?
Thanks,
Neda
