List of countServedRegions() Examples

Examples of countServedRegions()

org.apache.hadoop.hbase.MiniHBaseCluster.countServedRegions()
Counts the total numbers of regions being served by the currently online region servers by asking each how many regions they have. Does not look at META at all. Count includes catalog tables. @return number of regions being served by all region servers

Examples of org.apache.hadoop.hbase.MiniHBaseCluster.countServedRegions()

        TEST_UTIL.getConfiguration(), htdDisabled, SPLIT_KEYS);


    log("Regions in META have been created");


    // at this point we only expect 2 regions to be assigned out (catalogs)
    assertEquals(2, cluster.countServedRegions());


    // Let's just assign everything to first RS
    HRegionServer hrs = cluster.getRegionServer(0);
    ServerName serverName = hrs.getServerName();
    HRegionInfo closingRegion = enabledRegions.remove(0);
