Example 1 with ReplicationStatusKey

use of io.cdap.cdap.replication.ReplicationStatusKey in project cdap by caskdata.

the class ReplicationStatusTool method dumpReplicationStateTable.

private static void dumpReplicationStateTable() throws Exception {
    System.out.println("\nThis is all the HBase regions on the Cluster:");
    HBaseTableUtil tableUtil = new HBaseTableUtilFactory(cConf).get();
    ScanBuilder scan = tableUtil.buildScan();
    scan.addColumn(Bytes.toBytes(ReplicationConstants.ReplicationStatusTool.TIME_FAMILY), Bytes.toBytes(ReplicationConstants.ReplicationStatusTool.WRITE_TIME_ROW_TYPE));
    scan.addColumn(Bytes.toBytes(ReplicationConstants.ReplicationStatusTool.TIME_FAMILY), Bytes.toBytes(ReplicationConstants.ReplicationStatusTool.REPLICATE_TIME_ROW_TYPE));
    try (Table table = tableUtil.createTable(hConf, getReplicationStateTableId(tableUtil));
        ResultScanner resultScanner = table.getScanner(scan.build())) {
        Result result;
        while ((result = resultScanner.next()) != null) {
            ReplicationStatusKey key = new ReplicationStatusKey(result.getRow());
            String rowType = key.getRowType();
            String region = key.getRegionName();
            UUID rsID = key.getRsID();
            Long writeTime = getTimeFromResult(result, ReplicationConstants.ReplicationStatusTool.WRITE_TIME_ROW_TYPE);
            Long replicateTime = getTimeFromResult(result, ReplicationConstants.ReplicationStatusTool.REPLICATE_TIME_ROW_TYPE);

        }
    }
}

Example 2 with ReplicationStatusKey

use of io.cdap.cdap.replication.ReplicationStatusKey in project cdap by caskdata.

the class ReplicationStatusTool method getMapFromTable.

    HBaseTableUtil tableUtil = new HBaseTableUtilFactory(cConf).get();
    // Scan the table to scan for all regions.
    ScanBuilder scan = getScanBuilder(tableUtil, rowType);
