Examples with DisableTableProcedure org.apache.hadoop.hbase.master.procedure.DisableTableProcedure used on opensource projects

Example 1 with DisableTableProcedure

use of org.apache.hadoop.hbase.master.procedure.DisableTableProcedure in project hbase by apache.

the class TableNamespaceManager method migrateNamespaceTable.

private void migrateNamespaceTable() throws IOException {
    try (Table nsTable = masterServices.getConnection().getTable(TableName.NAMESPACE_TABLE_NAME);
        ResultScanner scanner = nsTable.getScanner(new Scan().addFamily(TableDescriptorBuilder.NAMESPACE_FAMILY_INFO_BYTES).readAllVersions());
        BufferedMutator mutator = masterServices.getConnection().getBufferedMutator(TableName.META_TABLE_NAME)) {
        for (Result result; ; ) {
            result = scanner.next();
            if (result == null) {
                break;
            }
            Put put = new Put(result.getRow());
            result.getColumnCells(TableDescriptorBuilder.NAMESPACE_FAMILY_INFO_BYTES, TableDescriptorBuilder.NAMESPACE_COL_DESC_BYTES).forEach(c -> put.addColumn(HConstants.NAMESPACE_FAMILY, HConstants.NAMESPACE_COL_DESC_QUALIFIER, c.getTimestamp(), CellUtil.cloneValue(c)));
            mutator.mutate(put);
        }
    }
    // schedule a disable procedure instead of block waiting here, as when disabling a table we will
    // wait until master is initialized, but we are part of the initialization...
    masterServices.getMasterProcedureExecutor().submitProcedure(new DisableTableProcedure(masterServices.getMasterProcedureExecutor().getEnvironment(), TableName.NAMESPACE_TABLE_NAME, false));
