Description

From http://54.241.6.143/job/HBase-TRUNK/org.apache.hbase$hbase-server/297/testReport/junit/org.apache.hadoop.hbase.master/TestDistributedLogSplitting/testMarkRegionsRecoveringInZK/ :

The assertion occurred on second line below:

    List<HRegionInfo> regions = ProtobufUtil.getOnlineRegions(hrs);
    HRegionInfo region = regions.get(0);

This meant that there was no online region at that moment.
