---------------------------------
Summary: NullPointerException in ActiveTimeSeriesCounter
Key: IOTDB-357
URL: https://issues.apache.org/jira/browse/IOTDB-357
Project: Apache IoTDB
Issue Type: Bug
Reporter: Jialin Qiao
Start a empty IoTDB, execute 3 sql:
{code:java}
SET STORAGE GROUP TO root.turbine;
CREATE TIMESERIES root.turbine.d2.s0 WITH DATATYPE=DOUBLE, ENCODING=GORILLA;
insert into root.turbine.d2(timestamp,s0) values(2,25.3);{code}
Kill the server and restart, then you will see:
{code:java}
