      Description

      When I run the schema creator tool of timeline service v2, then an error happened with the error message below:

      17/08/30 16:04:18 INFO zookeeper.ClientCnxn: Session establishment complete on server zdh175/10.43.183.175:2181, sessionid = 0x15e0d065a330019, negotiated timeout = 180000
      17/08/30 16:04:18 WARN util.HeapMemorySizeUtil: hbase.regionserver.global.memstore.upperLimit is deprecated by hbase.regionserver.global.memstore.size
      17/08/30 16:04:18 ERROR storage.TimelineSchemaCreator: Error in creating hbase tables: java.lang.reflect.InvocationTargetException
      17/08/30 16:04:18 WARN storage.TimelineSchemaCreator: Schema creation finished with the following exceptions
      17/08/30 16:04:18 WARN storage.TimelineSchemaCreator: java.lang.reflect.InvocationTargetException

      But I can't tell which error caused this exception with message.

      Then I find it only print the exception message in TimelineSchemaCreator

        try {
          ......
        } catch (IOException e) {
            LOG.error("Error in creating hbase tables: " + e.getMessage());
            exceptions.add(e);
        }
      

      I change it like this

        try {
          ......
        } catch (IOException e) {
            LOG.error("Error in creating hbase tables: ", e);
            exceptions.add(e);
        }
      

      finally, I get the detail of this error, and it's caused by a directory of hbase not created.

      17/08/30 16:03:42 WARN storage.TimelineSchemaCreator: java.lang.reflect.InvocationTargetException

      As the exception message is not enough to find out the error, so I think print all the information of the exception in TimelineSchemaCreator is better.
