Examples with ApplicationRowKeyPrefix org.apache.hadoop.yarn.server.timelineservice.storage.application.ApplicationRowKeyPrefix used on opensource projects

Example 1 with ApplicationRowKeyPrefix

use of org.apache.hadoop.yarn.server.timelineservice.storage.application.ApplicationRowKeyPrefix in project hadoop by apache.

the class ApplicationEntityReader method getResults.

@Override
protected ResultScanner getResults(Configuration hbaseConf, Connection conn, FilterList filterList) throws IOException {
    Scan scan = new Scan();
    TimelineReaderContext context = getContext();
    // Whether or not flowRunID is null doesn't matter, the
    // ApplicationRowKeyPrefix will do the right thing.
    RowKeyPrefix<ApplicationRowKey> applicationRowKeyPrefix = new ApplicationRowKeyPrefix(context.getClusterId(), context.getUserId(), context.getFlowName(), context.getFlowRunId());
    scan.setRowPrefixFilter(applicationRowKeyPrefix.getRowKeyPrefix());
    FilterList newList = new FilterList();
    newList.addFilter(new PageFilter(getFilters().getLimit()));
    if (filterList != null && !filterList.getFilters().isEmpty()) {
        newList.addFilter(filterList);
    }
    scan.setFilter(newList);
    scan.setMaxVersions(getDataToRetrieve().getMetricsLimit());
    return getTable().getResultScanner(hbaseConf, conn, scan);
}

Example 2 with ApplicationRowKeyPrefix

use of org.apache.hadoop.yarn.server.timelineservice.storage.application.ApplicationRowKeyPrefix in project hadoop by apache.

the class TestRowKeys method testApplicationRowKey.

@Test

    ApplicationRowKey rowKey = ApplicationRowKey.parseRowKey(byteRowKey);

    assertEquals(USER, rowKey.getUserId());
    assertEquals(FLOW_NAME, rowKey.getFlowName());
    assertEquals(FLOW_RUN_ID, rowKey.getFlowRunId());
    assertEquals(APPLICATION_ID, rowKey.getAppId());
    byte[] byteRowKeyPrefix = new ApplicationRowKeyPrefix(CLUSTER, USER, FLOW_NAME, FLOW_RUN_ID).getRowKeyPrefix();
    byte[][] splits = Separator.QUALIFIERS.split(byteRowKeyPrefix, new int[] { Separator.VARIABLE_SIZE, Separator.VARIABLE_SIZE, Separator.VARIABLE_SIZE, Bytes.SIZEOF_LONG, Separator.VARIABLE_SIZE });
    assertEquals(5, splits.length);
    assertEquals(0, splits[4].length);
    assertEquals(FLOW_NAME, Separator.QUALIFIERS.decode(Bytes.toString(splits[2])));
    assertEquals(FLOW_RUN_ID, (Long) LongConverter.invertLong(Bytes.toLong(splits[3])));
    verifyRowPrefixBytes(byteRowKeyPrefix);
    byteRowKeyPrefix = new ApplicationRowKeyPrefix(CLUSTER, USER, FLOW_NAME).getRowKeyPrefix();
    splits = Separator.QUALIFIERS.split(byteRowKeyPrefix, new int[] { Separator.VARIABLE_SIZE, Separator.VARIABLE_SIZE, Separator.VARIABLE_SIZE, Separator.VARIABLE_SIZE });
    assertEquals(4, splits.length);
    assertEquals(0, splits[3].length);
    assertEquals(FLOW_NAME, Separator.QUALIFIERS.decode(Bytes.toString(splits[2])));
    verifyRowPrefixBytes(byteRowKeyPrefix);
