Description

Under a YCSB load test (for HBASE-6295), we can have sporadic bulk of logs because of this:

      final RegionMovedException rme = RegionMovedException.find(exception);
      if (rme != null) {
        LOG.info("Region " + regionInfo.getRegionNameAsString() + " moved to " +
          rme.getHostname() + ":" + rme.getPort() + " according to " + source.getHostnamePort());
        updateCachedLocation(
            regionInfo, source, rme.getServerName(), rme.getLocationSeqNum());
      } else if (RegionOpeningException.find(exception) != null) {
        LOG.info("Region " + regionInfo.getRegionNameAsString() + " is being opened on "
          + source.getHostnamePort() + "; not deleting the cache entry");
      } else {
        deleteCachedLocation(regionInfo, source);
      }

They should just be removed.
