Examples of HServerInfo

org.apache.hadoop.hbase.HServerInfo
HServerInfo contains metainfo about an HRegionServer, Currently it only contains the server start code. In the future it will contain information about the source machine and load statistics.

Examples of org.apache.hadoop.hbase.HServerInfo

      // happen after check of MSG_REPORT_EXITING above, since region server
      // will send us one of these messages after it gets MSG_REGIONSERVER_STOP
      return new HMsg [] {HMsg.REGIONSERVER_STOP};
    }


    HServerInfo storedInfo = serversToServerInfo.get(serverName);
    if (storedInfo == null) {
      if (LOG.isDebugEnabled()) {
        LOG.debug("received server report from unknown server: " + serverName);
      }


      // The HBaseMaster may have been restarted.
      // Tell the RegionServer to start over and call regionServerStartup()
      return new HMsg[]{HMsg.CALL_SERVER_STARTUP};
    } else if (storedInfo.getStartCode() != serverInfo.getStartCode()) {
      // This state is reachable if:
      //
      // 1) RegionServer A started
      // 2) RegionServer B started on the same machine, then 
      //    clobbered A in regionServerStartup.
