      Follow below steps to replay the problem:
      1. change the SplitTransaction.java as below,just like mock the timeout error.

      SplitTransaction.java
            if (!testing) {
              MetaEditor.offlineParentInMeta(server.getCatalogTracker(),
                 this.parent.getRegionInfo(), a.getRegionInfo(), b.getRegionInfo());
