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. https://git-wip-us.apache.org/repos/asf?p=incubator-blur.git;a=blob;f=blur-core/src/main/java/org/apache/blur/thrift/BlurControllerServer.java;h=06f5ea3575c0b5797ff78ea65add62717edbd034;hb=b5eb4795d18d80c58fe25e863564548063b16921#l1074 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. Aaron On Fri, Apr 11, 2014 at 12:34 PM, Aaron McCurry <[email protected]> wrote: > What version are you running?
