Can't build and refresh job

[Yapu Jia]

Hi, all,

         I can build and refresh a cube successful in the past.
         After a segment build success,  I can't refresh or build the cube and 
query this segment data.
         The web tip is that:

[cid:image001.jpg@01D1AD32.80BDFDC0]

          And, the kylin.log is that:

                java.lang.IllegalStateException: There is already a building 
segment!

         I can use others kylin server to build or refresh this cube.
         And, when I restart this kylin server, I can refresh and build this 
cube. So, I think that maybe a bug.
         Can you help me to fix it.

Thanks,
Yapu
